for some reason the search engine is not working for me so a couple of quick questions

where are the relays and control modules for the heated seats located on my 88 5000CSTQ Avant

thanks

The 2 relays have green/orange stickers on them.

I don't believe so.

sit in the car turn the ign on and turn everything off that makes any noise.
Now with ign still on turn the heater seat switch slowly on... you should hear a small click sound . ( click means the relay is working )

actually i put my hand on them to feel they are working, which they are so need to look into where the power goes after the relays

so I guess the reason you are doing this is because you are getting no heat from the seats ??

If so 9 out of 10 it's caused by a brake in the small element wires found in the heated seat pad . The heated seat has two pads one for the butt and one for the back . It is usally the butt one that fails. If one of the pads has a broken wire neither of them will work. I know I have a write up on the process on this site.

problem found, tracked it down to the heater grids in the seats
