Heated Seats.

I know my drivers heated seat aint workin, and think the passenger one is as the dash lights dim a little at start up. The lights on the buttons come on on both when pushed so has anyone any ideas as up here in the open meadows of the pennines, it would be useful!!![/b]

first of al check the wires under the seats are connected, you could disconnect them and check you are getting voltage through when you turn them on, if you are, its probable that the wires in the heating pads have broken, which inolves dismantling the seat (not actually that hard to do)
If you don't gewt voltage then you need to look at the connectors on the switches on the dash i would think.

If I don't have an Voltmeter to test for current - could I use the old 12v bulb and wire fixed to terminals instead?

Both my switches light up when 'on' but only passenger heated seat works.

If if is the wires in the seat base bust - any ideas how I'd find them/fix them please.

Won't be long before Jack Frost is with us so could do with getting sorted asa!

Thanks in advance (hopefully).

I am also very interested in this. My drivers side and passenger dont work. Passengers is something inside I believe and drivers is the wires have been pulled out of the back part so i ned to investigate where they go!

After you confirm the switch...

As I recall, the thermostat is commonly at fault, and often needs to be replaced. Next up is broken wires - you need to solder more wires in this case.

Both require you to "skin" the seat to get the the relevent parts, IIRC

BTW: Go buy a volt meter - you can get them a cheap as a fiver from Maplin!!!!

When I asked about my seats at the dealership, the first thing the parts guy said was "thermostat" so I'd definately check that first as Gaz said.

where is the thermostat?

Same thing is happening to my seats

. I do get voltage out of the wires but still the seat dont heat up. How do u actually strip the seat down? Does it mean taking the whole seat out the car?

It's far easier that way. You need a set of torx bits to remove the seats, then the "skin" is held on by small wire clamps. Cut them off and use cable ties at reassembly. If you insist on doing the least possible you might get away by peeling back the cloth from the rear until you've exposed the thermostat, which is the usual culprit.

This is old but, are there any more repair instructions for these heater pads. Removing the seat is fine but how do I go about finding the problem if it is in the heater pads? I've binned my old interior already so dont have spares but are damaged heaters usually repairable?

Thanks,

Disconnect seat from wiring loom, insert voltmeter in seat half of plug, check for continuity. If OK, the trouble is in the car. Do note that there are two pads in each seat, one for the backrest and one for the seat. The one in the backrest doesn't have a thermostat and is usually OK. (at least I've never seen one broken)

If v-meter indicates continuity(around 2 ohms I believe) in both pads then insert meter in car half of plug. Set meter to DC volts, start engine and push seat heater switch. Meter should now read about 12 V or something in the car is broken.

The most common fault is the thermostat, either the connections or the actual thermo. For a crude fix one can simply put a jumper lead across wher the thermo was, but that puts you at risk of overheating and potentially even fires. Best is to fit a new thermo. The thermo should be closed (continuity across terminals) when cold and open at about 27 deg C. Once open it doesn't close until below 15 deg C or so.

Cheers Capain! I'll be taking the seat out tomorrow then.

Hithis is my first post so i hope i have done it ok.

How do you know if your car has heated seats? I can't find any buttons to turn on the rear seats at all.

THanks

voltmeters measure voltage

ammeters or milliammeters measure current

ohmmeters measure resistance and continuity

multimeters can measure all 3 quantities by selecting setting and range

Wowser!!!!!!

So maybe I SHOULD have said "use multimeter in its appropriate setting to check voltage/continuity/resistance" instead, big deal.

AFAIK rear seats are never heated in a stock vehicle, only front. Still I wouldn't be surprised if someone somewhere had taken the trouble to put heaters in rears as well.

I knew what was meant!

Is that the same voltmeter that is fixing your starter motor?!

- there are no heated rear seats. The front heated seat buttons are on the centre console in front of the gearstick, next to the long range light switch.

No its not the same voltmeter thats the big silver switch thats fixed my duaghters 480
