[Sir Sideways]

My drivers heated seat doesnt work, ive checked the fuse but thats fine, the wiring is connected. Height adjustment works fine up and down. I set the heat controll to 6 the light comes on but nothing happens, the passenger seat heats up like normal.

Any Ideas on what to do next?

Many thanks

Most likely culprit is the heater mat or thermostat.

Is it the seat base or back, or both that don't work?

[Sir Sideways]

both seat and back dont heat up

Assuming face lift seats are wired the same as earlier cars, the 2 mats are wired in series with each other. My pre face lift seat was cured by cutting out about the first 2" of the base heater element that had burnt out. My previous Senator's seat was cured in the same way. Take the seat out & have a look - the worst result is a seat heater that doesn't work!!   The seat is bloody heavy though

It's probably the integral thermostat in the mat.  I guess it switches both mats.  However, when this goes, it normally fails switched on, causing the mat to overheat and potentially a fire!

First check for voltage at the connectors under the seat.  Compare with the other side with the settings the same.  (Don't unplug the airbags accidently, if you have them).

The connector will look something like this.  




The airbag connectors are the outside yellow pair.  The heater mat wires are the centre four, I believe.

Are they leather seats?

[Sir Sideways]

yes they are leather, and they do have airbags.

ill go and check the voltage now.

Thank you all so much for the help

[Sir Sideways]

Right, i checked the voltages on both seats and they both gave a reading of 28v (btw for future reference it was the green plug, i switched them on and off to varify) . i set both seats to no.5, as the passenger seat warmed up i felt where the heat was and felt in the same place on the drivers seat but no part of the drivers seat warmed up at all.

I'm pretty certain you'll have to remove the seat and bottom cover to inspect and test the mat.

New ones are very expensive, but they do come up on Ebay occasionally.

I have got instructions 'somewhere' to remove leather covers.  I'll try and dig them out.  Unless anyone else can tell you.

By the way, before you disconnect any airbags, disconnect the battery first and wait a minute.

[Sir Sideways]

Ok cheers Buddy, your help is much appreciated

Many Thanks

I would also appreciate some instructions for removing the leather covers.

My drivers seat has suffered the same fate.   I was really lucky though and was able to pick up a replacement cover on eBay which was brand new.   It just needs fitted and plugged in.

If my memory serves me correct i phoned Vx with the part no. and was quoted over £300!

The heating pad is sewn into the leather covers, but i think with the standard seats you can replace the heating pad on it's own.

I have a problem with the drivers side heated seat. The seat heats up but its like sitting on a George Foreman grill you can smell the flesh burning [smiley=laugh.gif]. Its a leather seat. Any info would be much appreciated

[Hillper]

Same applies as above.

Thermostat is dead.  You need a new pad I'm afraid.

But don't use it, or you may start a fire!

Again, passenger seat fine, driver's seat touch and go.

Sitting still it works fine, leaning forward it cuts out (switch light goes out) and this will repeat a few times before the fuse blows.  I assume that there is a break in the bottom pad - could it be repaired, joined or bypassed ?

BTW sitting still is not an option.

That's exactly what happened to mines before it gave up the ghost.  :-?

Am I right in thinking that on the pre facelift the pad is fixed to the leather cover meaning you have to change the whole seat cover. [smiley=sad.gif]
