My 1994 Volvo 850 Turbo's driver's seat warmer is not working. The passenger's seat warmer does work. How can I fix this problem? Could it just be a fuse? If not, what, how, and where can I find out how to fix this? Thanks.

Check under the seat to see if the wires have disconnected. Should be a red and white wire. The wires coming lose are common and easy reconnected.

I checked and it's not this. Is there anything else that I, on a kinda limited mechanical scale, could do to fix this? I'm not one to begin disassembling wiring through the dash or firewall. Thanks for your help so far!

Heres how to check the wiring. Those two wires (red, red&white) are suppose to be connected to the thermostat in the seat bottom. From the bottom of the seat, in the middle, stick your finger/fingers up in the hole in the foam rubber and pull down the white plastic piece that is holding the thermostat, connect your wires and then put the thermostat back up in the seat. If not that it could be the grid in the seat has gone bad.

I re-checked some of these wires today, but I realized that there are a lot of other wires coming from other places right under where you would reach for the seat-adjustment(fore and aft) bar on the passenger side. I was able to easily grab a red and black wire that went into a connector box with a thin, white rectangular piece of plastic on it. Is this the thermostat? If not, how do I gain access to the underside middle of the power-operated driver's seat? Can I just put the seat in it's full-back position and be able to get to it? Thank you-I want to pursue this possibility before replacing the seat. Thanks again!

Heres a link about the seat heaters. <A HREF="http://www.volvospeed.com/vs_forum/index.php?act=ST&f=3&t=769&hl=seat+heater&s=9a054d1ae1eff69cc3ffdac445c4c130" TARGET="_blank">http://www.volvospeed.com/vs_forum/index.php?act=ST&f=3&t=769&hl=seat+heater&s=9a054d1ae1eff69cc3ffdac445c4c130</a>

I had my drivers side seat heater replaced once at Volvo a couple years ago. Wonder if they just reconnected it... hope they are honest about that. Too late now, damb! Oh well, it works <IMG NAME="icon" SRC="http://********************/smile/emcrook.gif" BORDER="0">

Re: 850 Turbo Driver Seat Warmer Not Working (Spearzy)

I tried again this weekend but I can't get my hands to the correct place because I can't get around the seat motor. Has anyone else had this problem and if so, how have they dealt with it? I guess I could try to find someone with smaller hands to do it for me........?
