I just bought a 2005 Sebring, perfect body, non smoking, but plagued with tinny sounding noiseson almost any road surface. It is not like a bushing noise, and seems to be locate behind the engine/tranny but out to the side.I know the repair for the heater control is bad, only operates at full speed. Passenger side window not operating. Would it be possible to squirt som contact cleaner in around it. Roughly 125K miles 200K km.
