I have purchased the cooling fan relay for this vehicle at least 10 times. Every stinking one that I get from Dealer has a different reading across 85 and 86.
Today I bought a new one again and it does not measure 68 ohms like it should. It measures 71 ohms. The other 5 or 6 that i still have laying around measure anywhere from 74 ohms up to 85 ohms.

Some of you may say that it does not make that much difference. but i can yell you that if you do not have a high speed cooling fan relay that meassures 68 ohms across 85 and 86, your high speed cooling fan will not come on for high speed. The only relay that i have now that measures 68 ohms across the coil came from the relay that is below the TIPM. This is the very same relay that I have been unsuccessfully trying to get anyone to help me identify what it is there for.

it is a OMRON relay marked 68093292AA. This is the original OEM Omron relay that should be used and not the cheap knock off and unreliable,inconsistent, made in BFE that dealer is selling as OEM.. This relay the OEM relay made by OMRON is the only relay that works and successfully turns on fhe highspeed fan when it is supposed to come on. When it fries I am SOL unless I steal one from a brand new Dodge Grand Caravan.

I just called FCA in Auburn hills and they told me that they do not deal with parts. She told me that I needed to contact dealership and I told her that it was not a dealership issue because the same relay has come from 3 o more dealerships in a bag marked Mopar.

She said that is not something that they deal with and that I had to contact Mopar directly.

Dave thank you, but all due respect this is a not a customer relations issue. it is a Mopar Quality Control, Quality Inspection issue and the address you gave me aeems like a catch all for pissed off consumers.

Does Mopar not have a engineering or a quality control team?

The fan control relay may be stamped 68093292AA but that is not the part number.
The radiator fan control relay is serviced as Mopar part # 56007080AB. That is the part number that you should have.
If you keep replacing that relay and keep having the same problem, then I don't think that the relay is the issue. Winding resistances can vary by a few ohms.
The high speed fan relay is outside of the TIPM. I found a Mopar part # of 4692139AA? Is that number stamped on that other relay anywhere?
There is also a PCM flash for false (high) oil temperature readings that was released last October.

Who did you call in Auburn Hills? Have dealt with Customer Relations several times and they DO respond to parts problems, but you may have not talked to the correct people. Also see the previous item about the valid part number for the relay you seem to be looking for. Contact a Mopar person later today and was told you are not getting the correct part because of the number thing. Good luck.

How high for the oil temp ? the part nber I have and the one that I am always sold is part number 56007080AB. but, the relay 68093292AA is manufactured by Omron and it is the original relay for this vehicle. The 56007080AB is the replacment i believe there is one with and one without the bracket and the 6809 relay Omron does not have the numbers 1 and 2 or what ever the numbers are that are associated with the coil 85 and 86. Supposedly these are the same relay except for those differences. In the TIPM all of the small relays that consumers cannot order themselves all have Omron on them. I do realize that the high speed relay is outside the TIPM. It is the relay that i keep having to replace. A couple of times the relay itself swelled up much like a capacitor does that goes out on an ac compressor on an outside unit for a home.

I did not know about the flash for the oil temperature and I had noticed the oil temperature being to high, in my opinion. However, with all of that being said the high speed fan should come on the air conditioner is on and the engine is rising above opetating temperature. If a flash of any sort will straigtened this out then the $140 it will cost me to get done will be worth it. thank you for commenting and providing that information

thank you. i emailed Mopar parts customer service in Auburn Hills.

My point about the relay being marked with Omron is that I still would like,to be able to purchase an Omron relay since the coil resistence of their relays is correct and it is not manufactured by Mopar who very well could be farming out the manufacturing of this relay to China or Mexico who may not have the best quality standards

. . . . Some of you may say that it does not make that much difference. but i can yell you that if you do not have a high speed cooling fan relay that meassures 68 ohms across 85 and 86, your high speed cooling fan will not come on for high speed. . . . . .
Terminals 85 and 86 are the control circuit on the relay. The TIPM does NOT have logic such that if the resistance in this circuit changes by 3 - 5 ohms, it will disable the circuit and cause the high speed fan relay to not engage. This is an incorrect assumption. There could be other circumstances that are present and not allowing the high speed fan to engage.

How do you know that the high speed fan relay is not working? Are there any diagnostic codes in the PCM indicating a problem with the radiator cooling fan circuits? (codes P0480; P0481) Not having a CHECK ENGINE lamp illuminated is not sufficient. A scan tool needs to be connected to the diagnostic port and the PCM memory searched for any and all codes.

Go back to this link I posted on Apr 21, 2017. I posted a chart which shows the conditions that will cause the PCM powertrain control module) to issue commands to the TIPM (totally integrated power module) and engage the radiator fan.

Engine Coolant Temp Sensor Options (at https://www.allpar.com/forums/threads/engine-coolant-temp-sensor-options.167500/page-2#post-1084853627 )

In the chart there are 3 input parameters that the PCM interprets before it issues a command to the TIPM to engage the radiator fan. These are engine coolant temperature, air conditioning system pressure, and automatic transaxle fluid temperature.

Are you thinking that when the A C system is first activated the radiator fan should immediately launch into high speed fan operation? That is an incorrect assumption. Referencing the chart I posted on Apr 21, when A C system discharge pressure reaches 250 psi, the radiator fan will operate in low speed. When the pressure reaches 300 psi, then the fan should go into high speed operation.

If it is a moderate temperature day with sunlight with ambient temperature below 85 deg F, the radiator fan running on low speed should provide sufficient air flow across the condenser to keep pressure within desirable operating limits. The high speed operation of the fan will NOT come into play.
I looked at weather conditions in the Dallas - Fort Worth area and it seems temperatures are still moderate with highs in the mid-80 deg F range.

Engine coolant temperature needs to reach 230 deg F before the radiator fan goes into high speed operation.

What is your basic concern? Are you afraid that the engine is overheating? Are you using the instrument panel gauge as your source of deciding if the engine is overheating? You really need to connect a scan tool (not a code reader) to the diagnostic port and view the engine operating temperature that the PCM sees.

If the relay is noticeably swelling, it may be from over-current creating too much heat at the internal contacts.
In my experience this is not an internal 'relay' issue, but more of an external excessive motor current draw issue?
Make sure that your wiring is correct. It is a fairly simple 2-speed motor circuit.

Buying a used factory manual might help you out in the future. In the electrical section they have the wiring diagrams and ground/splice locations, and they show the relay locations on the car body. And they name the use for each relay [ASD relay, etc]. No part numbers are given.

I have to admit I was also thinking it could be a systems issue — since most things are, and these parts work fine on everyone else’s vans.

It does help if you speak to the right people. I only know how to mail them, not how to call them. You could try Official Mopar Site | Service, Parts, Accessories & More (at https://www.mopar.com/en-us.html ) which has a Chat With Us option in the gray area near the bottom. They also have an Email Us. As far as I can tell, the phone numbers are just the generic ones. The chat is most likely to get you to a Mopar person.

AllanC is correct, the coil resistance is NOT the issue. you have a nominal 12.6 volts across the coil. At 68 ohms, that's flowing 185 milliamps. At 71 ohms, it's flowing 177 milliamps. There's no way that that difference will determine whether the relay closes or not. What is happening here is that the PCM is not turning the relay on when it should. And that's what should be investigated.

I agree with both Bob and AllenC. Sorry if this sounds harsh but you have stated you have replaced the relay 10 times. When do you realize that it might not be the relay but what is controlling the relay?

I have been in electronics for many years and those resistance numbers for the coil of a relay are not very far off. They will vary a few ohms.
