Neither of my heated seats work either. (I bought the 97 GLT Wagon in April and wasn't able to test them out.) When following other posts, I checked what I could. Fuse is OK because it is shared by another function that works, switches both light up, wires underneath all seemed connected so I went to the thermostats. Passenger therm. was disconnected so when I plugged it back and tried it - no luck. Driver therm. had a broken terminal. I moved the passenger therm. over to the driver side and still didn't receive any heat. So, both seats don't give the heat.

I decided to replace the therm. with the broken terminal. Went to the local dealer and they had 1 heck of a time getting the actual part. In fact, they said the passenger side therm. was a different part# and specs. than driver side (something about voltage???). Anyone aware of this? I would have thought they were interchangeable. Bottom line is that I ordered the part and it cost $24.00 just for the passenger side therm.! I'll try this fix and if it doesn't work, I may have to bite the bullet and bring it into them for more diagnosis. Otherwise, where are you ordering the heating elements for that low of a price. I may get ambitious and try myself if the dealer quotes too rich for me to get them fixed. Thanks!

Has anyone installed seat heaters in a Volvo not originally equipped? I have a 98 S70 GLT with leather but no seat heaters. Is it prewired from factory so that it could be upgraded?

Make sure the heater element cicuit is open before you proceed too far. Take the seat out of the car, where the heater plugs into the power supply you can use a continuity checker. If the circuit is open it is fried. Cut the hog rings off with side cutters. Pull the cover off, remove the old heater, slide in the new one, put the cover back on. Attach the cover with good quality ty-wraps and re0install the seat. easy in 2-3 hours.

The OEM units are less than $60 each mailorder. It is curious that they both quit at the same time. I would do more checking of fuses and thermostats before spending $$ to replace elements that may be fine. I replaced the driver side element on mine last year. The element had broken and had burned a hole in the seat foam. Luckily, it did not burn a hole in the seat cover. It is somehwat of a tedious job, but you can do it yourself and save big. I used snap ties to put the seat back together.
