Heated seats in a non heated seat car?
Posted March 30, 2012 at 10:19 pm
The main thing I am trying to find out right now is for the driver side. When I looked at the car I got the seats out of, it had 3 wires coming from the car on the black plug, same as mine has. And like I said above, the plugs from both the seat and the car plug right in. Yet the seat will not turn on when I hit the button on the seat. Is there another element that I might be missing? Maybe under the dash or something? I looked at the fuse panel on the donor car and it had one more fuse then mine and the fuses are in different locations, but the panel itself looks the same. So I put a fuse in the spot mine was missing one and still nothing.
Would love it if someone could shed some light on what I may be missing so I can start looking for it at the scrap yards, or just know what to buy in general!
Thanks for any help.

I did find this online
Connector 206 is a 2 pin with black for ground and:
Early build = Red w/Light Blue stripe.
Normal build = Red w/Light Green stripe.
This connector is only used for the seat height adjust. The seat airbags and heated seats use different connectors. If the seat does not work, check for the 20amp circuit breaker located in the fuse panel. It's at the top left, number 2. In addition check for fuse number 6 in the underhood fuse/relay panel. Fuse number 4 in both panels is used if the PT was originally set up for heated seats.
If you don't find the connector or wiring under the seat you can power it yourself. Run your own fused wires to the switch. Pins 2 and 5 go to ground. Pins 3 and 4 should already go to the motor. Pin 6 goes to power through a 20amp fuse.
Power Outlet Problem - The power outlet is on the same fuse (#20) and ground (G203) as the cigar lighter. The lighter is switched with the key and the outlet is on all the time. If one works and the other does not, it will need a trip to the dealer for a warranty replacement.

HEATED SEAT SYSTEM - DESCRIPTION
Individually controlled, electrically heated front seats are available factory-installed optional equipment on this model. Vehicles with this option can be visually identified by the two separate heated seat switches mounted on each of the seat cushion side shields. The heated seat system allows the front seat driver and passenger to select from two different levels of supplemental electrical seat heating, or no seat heating to suit their individual comfort requirements. The heated seat system for this vehicle includes the following major components, which are described in further detail later in this section:
- Heated Seat Elements - Two heated seat elements are used per vehicle, one for each front seat. The heated seat elements are integral to the front seat and seat back cushions. Refer to the description of the heated seat elements later in this section for additional information.
- Heated Seat Modules - Two heated seat modules are used per vehicle. One module is mounted to each of the power seat cushion pans, under the forward edge of each front seat. Refer to the description of the heated seat module in the electronic control modules section of the service manual for additional information.
- Heated Seat Relay - One heated seat relay is used per vehicle. The relay is located in the instrument panel fuse block, on the left lower side of the instrument panel.
- Heated Seat Sensors - Two heated seat sensors are used per vehicle, one for each front seat. The heated seat sensors are integral to each of the heated seat cushions.
- Heated Seat Switch - Two heated seat switches are used per vehicle, one for the driver and one for the passenger side front seats. The switches are mounted to each of the front seat cushion side shields. Refer to the description of the heated seat switch later in this section for additional information.
HEATED SEAT MODULE - DESCRIPTION
Two heated seat modules are used on each vehicle equipped with the heated seat option. One heated seat module is located on each power seat track, where they are secured with two push-in type plastic fasteners. The modules are contained within a small, rectangular, molded plastic housing with a single connector receptacle that allows them to be connected to all of the required inputs and outputs through the power seat wire harness.
The heated seat modules are electronic microprocessor controlled devices that are designed to monitor the inputs and control the outputs of the heated seat system. The heated seat modules are programmed to provide two levels of heating for each front seat: a Lo temperature set point of about 36° C (97° F), or a Hi temperature set point of about 41° C (105° F) The heated seat modules are also programmed to perform self-diagnosis of certain heated seat system functions. Refer to heated seat module diagnosis and testing for additional information.
The heated seat modules cannot be adjusted or repaired. If a module is damaged or faulty, the entire module must be replaced.

Just wanted to share what I have figured out on the car so far.
My wires going to the seat, coming from the car itself, match the wiring on the donor car. I found out I do have a heated seat fuse under the hood and it is in place. According to the donor car under the dash fuse panel, fuse 4 and 17 work the heated seats. My fuse panel shows them as blank, although they will hold a fuse. I tested fuse 4 after I put it in and I have no power to it. In turn, I don't have power to the wire on the seat plug either. Only have power to the up and down feature.
My owners manual has instructions for heated seats, although it say's it is an optional option. I am wondering if there is something in the wiring under the dash, near the fuse panel that just needs to be connected in order for my seats to work. I know in the old days they made cars all the same and just didn't plug in the wiring or you had to buy a harness to connect to the under dash loom for what you wanted to ad later.
I am now off to look for some wiring diagrams. My car is a 2001 and the donor was a 2002. So I wouldn't think they were to far off as far as wiring. But I will search for both.

All I need to do is put the fuse in the number 4 fuse hole and the relay in the empty relay spot on my car. The relay did the trick.
Thanks for all the help!!

I've just fitted a set of heated seats to my 2004 Cruiser (UK spec, right hand drive!) and I appear to be having a similar issue. The wiring was all in place, the seats bolted in fine and all the plugs and connectors fitted perfectly, but the heated seats don't work.
So I'm guessing I am also missing a relay...
Would anyone be able to provide me with a photograph of the relay that's required (in situ)?
Thanks in advance

I went to a local breakers yard and pulled a relay from the fusebox under the steering wheel - this was missing in my car.
After plugging the relay in, the green backlight on the heated switches now lights up (they weren't lit before) but the switches still don't function.
Anyone know what else I might be missing here?

Welcome to Allpar. Thank you for the additional information. I didn't want to post until you investigated your situation a little further. I am sure that Domestic and Export PT's have their differences. We didn't have the 2.0L or diesel engine option over here.
Justcruzin's experience was different as their PT already had more heated seat circuit support than I would have expected in a non-equipped car. Sometimes the wiring and support components for optional accessories isn't even there on a base vehicle.
