jdlc Posted January 6, 2008 Report Share Posted January 6, 2008 Okay, suppose you get a hold of a parts car with working heated seats.Seats are different color, so can't use it. Besides, my seats are in very good shape and has air-bag.Is it possible to take the elements, thermostats, relays and wires from the parts car and make my regular seats heated? Last time I checked under the console of my V70, there seems to be wires in the area where the heated switch should be (near the coin tray). There are also wire terminals under each of the front seats, is it for heated seats pre-wire? The color of the terminals are 'semi-transparent' white.Anybody with V70/S70 with heated seat that can take the time to look under their seat to see if in fact the said white terminals are for heated seats?Better still, anybody done it for their V70/S70?btw, I did search and found a similar query about making the rear seats heated.Help a brother out to make my wife love me more, lol.Thanks,OrleeC Link to comment Share on other sites More sharing options...
BEJinFBK Posted January 6, 2008 Report Share Posted January 6, 2008 You should be able to just swap seat skins to use the donor seats.As for the wiring, most car builders these days load up all the levelswith the same harness to make'em easier to build and add upgrades at the dealer. It wouldn't surprise me if all you need is a fuse a relay,some switches and seats with heating elements. With luck, it'll all Plug N Play! And your wife will love'em...Oh Yes...Next time I have mine inside, I'll take a look. Link to comment Share on other sites More sharing options...
Ozark Lee Posted January 6, 2008 Report Share Posted January 6, 2008 Other than the switches most of the wiring should be there. Getting under the "skins" is a chore but it can be done.Your car has SIPS so be sure to remove a battery cable and properly defeat the airbag triggers.Here is a writeup I did that gets you most of the way there. It was on a non SIPS '94 but I think the same things apply.http://www.matthewsvolvosite.com/chat/phpB...p?p=30367#30367...Lee Link to comment Share on other sites More sharing options...

You can hit the side SIPS sensor with a hammer while it's out of the car and the airbag will go off. Link to comment Share on other sites More sharing options...
r850glt Posted January 6, 2008 Report Share Posted January 6, 2008 Make sure you use the red safety clip to disable side airbags when doing the swap. the clip is located beneath the trim where seat controls are. Link to comment Share on other sites More sharing options...
mbsl98 Posted January 7, 2008 Report Share Posted January 7, 2008 Just to avoid confusion for those with pre-96 850's: SIPS and side air bags are not the same thing. SIPS is the side impact protection system that has been in all Volvo's since at least 1992. It is part of the structure of the car, with heavy cross beams to carry side impact loads into the center tunnel of the car. Air bags were added as an option beginning in '95 (standard on the '95 Turbo only - an industry first). Those say "SIPS Air Bag" on the plastic covers at sides of front seats. If it doesn't say Air Bag, you don't have to worry about airbags going off when you are working, but if it does say it, you need to remove the plastic cover and insert a supplied locking pin before doing anything further on the seats. from '96 on, all Volvo's had side air bags as standard, so be careful all the time with those.

NyteMusic Posted January 7, 2008 Report Share Posted January 7, 2008 On a related note - I have a '96 Turbo, and I installed a set of seats from an R (I think it was a '97).The R seats have a plug receiver in/under the front that holds two plugs. My '96 only had one.I pluggged in the one harnes I have into the receiver and: no heatI would have thought the later car would have had a simpler wiring setup, not a more complex one, so maybe the seats are from a '95?Anyone have any ideas?(fwiw: the seats look so damn good it's worth it, even if they aren't heated! :) Link to comment Share on other sites More sharing options...

So your old seats are heated and you have the switch and all I suppose?Then that is strange. Link to comment Share on other sites More sharing options...
drlava Posted January 7, 2008 Report Share Posted January 7, 2008 I have installed aftermarket heating pads on my '95. it's straigtforward.If your elements are good, use a multimeter to measure the resistance across the element and it should read around 10 ohms +/- 5 (open circuit indicates sticking temperature cutout or open element). Likewise, on the connector going into the elements with the switch on it should read 12V. If either of these is not the case, you know which side of the circuit to troubleshoot.

Or as I am hoping, are 850's pre-wired for this? Link to comment Share on other sites More sharing options...
drlava Posted January 7, 2008 Report Share Posted January 7, 2008 Yes, there was already a harness. I bought switches, and made an adapter for the seat heater connector, because the heaters I installed weren't OEM. That was pretty much it as far as wiring!

That was pretty much it as far as wiring!Sweet, this is what I'm hoping for.I hope the same is true for 98 V70, I do have unused plug under each seat (white connectors as I mentioned), so if it would work like you said, all I need is a pair of switches (also saw pre-wiring for it under the center console) and donor seats with heater elements and thermostats.Thanks!And many thanks for all your responses guys (above).
