Driver's seat heat pad
01. Sep 2011 at 14:34

Hi guys

Last time I asked this (about a year ago) nobody seemed to know the answer.

My seat heater only works on full power. Great for a layby fry-up, but a tad uncomfortable to sit on!

Irrespective of the switch position - 1 to 5 - it is always on max (it turns off ok, and the switch doesn't feel as if anything inside is broken). Not knowing the circuit diagram it is all but impossible to fault-find. And knowing how everything else works on Miggies it's probably controlled by a microprocessor somewhere!

If anyone's got a detailed schematic of the circuit (together with component locations) it would be great. Failing that, can anyone suggest things I can try?

Cheers all,
Gaz

Maybe swap switches & see if the problem stays or transfers to the othe seat.

Not too bad by the look of it. Thumbs Up!

Doesn't look too bad, no. And the heater switches do look like they could be both the same too.

Not without removing the dash surround to unplug the sockets from the back, which is doable, I did wonder if the switch might have a facia that unclips. The switch itself will just pull out. It it can be got at without damage.
