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

Mine are the older on or off so this is a guess.
Are the switches for each side the same? Maybe swap switches & see if the problem stays or transfers to the othe seat.  :-/ :-/

Might be worth a try - although I bet there's a helluva stripout involved to get to them!!

Nah, takes about 10 mins to get to them  :y

Not too bad by the look of it.  :y :y

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

Switches are handed to fit the dash surround. I have a similar issue on mine.

But will they actually plug into the loom for testing?  :-/ :-/

Not really, the edge is angled, they slot in too, so you can't really pull out any loom to plug it in, without it being fitted  :(

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.

I shall try to remember to pop some replacement switches in for Newent, if you want to try?  Sure I still have Goldie's

What, overheating seat? Was it a faulty switch in the end?
