Anyone have any idea what causes this? My guess is one of the seat heaters is broken and shorting. So my next step would be unplug the heaters and check with an ohm meter? Thanks! Dave

My wife is still yelling about the seat heaters, nobody has any idea how to fix it?

Buy a new heater element and have an upholstery shop install it.

Well, I'd rather know that it is the problem! Can the element be checked with an ohm meter?

N_Jay

I am sure it can.

Does it blow the fuse right away or intermittently?

I am not sure what you are looking for. It is either shorted to ground, shorted to itself, or the wiring going to it is shorted.

I would say unplug it and see ifteh fuse still pops, but these cares are soo damn smart it probably won't energize the circuit after you disconnect the wiring.

Maybe put an ohmmeter on it and then wiggle in the seat and see if it jumps around.

Or test from the element to ground and do the same thing.

Haha, you funny. It doesn't blow right away. I have found this thread

I think it has what I need. Thanks!

Good write up, except that was for a broken connection.

Blowing fuses indicate a short not an open.
Fix may be similar just the wire is touching some metal and has not broken yet.

Well her bum is still cold because back in 2009 you said the following "So my next step would be unplug the heaters and check with an ohm meter?"

WTF you been doing for four years, can't afford a multimeter!!!
