Just joined Saabscene and am enjoying reading all the forum messages.
The drivers heated seat on my 9000 Aero is not working. I checked the price of a new element with the dealer (£150) however they said that they very rarily go and it may be just be a relay.
I can find the relay for the passeger seat but not the drivers. Can anybody help?

It is usually a broken element which is pretty easy to fix. You just remove the seat, unclip the hooks that hold the squab leather, lift it up then look for the burnt bit.

Once you've found the burnt bit, scrape away the foam, clean it up and resolder.

I'm surprised they said it rarely goes, the seats in both my Saab's have failed, one twice and i've also had 2 seat switch failures.

The one easy thing you can try before spending time dismantling the seat is to pop an ohmmeter across the yellow and black pair on the seat connector or at the connector behind the seat heater switch.

The resistance should be about 0.2 ohms. Obviously if this is correct then it's not a broken element.

One of my switches failed in an open state, the other in a closed state and I didn't notice the latter until I drove the car on the Monday morning when I drove it for longer than 10 mins. I was the guy driving through a frosty Reading town centre with the windows open and I was literally sweating because the thermostat wasn't turning the seat off. When I arrived at my destination I had to unplug the switch and then spent some weeks with the switch dangling out of the dashboard so that I could manually operate the heater.

Correction, 2 ohms, not 0.2 ohms.

Yeah - I was all set to fix the pad but one of the wires that was being bent back and forth with seat movement had broken.
Certainly wasnt obvious as the break was still quite buried so take your time and step through as many checks as you can.
(If the actual pad itself has gone, there should be some charring evidence on it)
