Sorry for another heated seat post. I have been lurking for a while now as I have been trying to find for myself.

but my heated seats seem only to work when they want and only for a minute or two.


have been trying to research but can not seem to come a cross a similar post please help!

Check out the service manuals, you may find the exact information you need. I found the heater diagram there under Seats (03 Coupe). Seems like you should check the 10A fuse #38. It could also be a faulty relay, or temp regulator... in which case you would need replacement parts.

 

Thank you for your help and time.
I have been trying to look thru the manual and can not make heads or tails of it lol.
I will check the fuses and relay as stated.
It is just very weird that they only work when they want and only long enough to feel them get warm and shut off

 

There is a thermostat in the lumbar section of the seatback, temperature should fluctuate from 95F to 113F

Since the seats ARE WORKING the problem is not in either the power delivery circuit, the switch, the heating elements. Your problem definitely sounds like a thermostat issue and you might have failing thermostats or someone may have spilled something on the seatback or damaged it in some way.

Do BOTH seats exhibit the same problem?

 

Yes they both have the same issue.
weirdest thing I have encountered with heated seats in general. Lol

 

The light stays on the entire time on the switch though correct?

 

Yes correct
