So I've had my 04 LB7 for a few weeks now and when I test drove it and bought it the same day the seat heater worked fine and it wasnt working so last night I took it upon myself to replace the bottom seat heater pad on the driver side seat that your butt goes on and it was a PAIN and i got everything hooked back up and its doing the same thing it did before, which is ya turn on the switch and it turns off within 5-15 seconds and I hear a clicking under my seat when i press it and the passenger side works fine! So what should I do to try and fix it or what is the problem any help or advice is much appreciated!

 

does it have a relay or a fuse that you can check. usually relays make a pretty loud click that you can hear. it almost sounds like a short to me somewhere in your wiring. check along the wiring where the seat slides on the rails and make sure there are no bare wires or rubbed through spots. i would also unplug your other seat and try the old seat warmer on that side. just plug it in on that connector and see if it has the same results or not.
