hi, i seem to have a problem with my seat heaters, every seat heater switch i press the light on the switch flashes, i can hear the click of a relay but they wont stay on any help would be great as here the UK Hummer experts are a bt thin on the ground

BTW its a H2 2004

thanks

 

Have the same EXACT situation with mine, got it diagnosed yesterday at HUMMER dealer as a bad driver's seat heater element shorting, causing failure on whole circuit. They've ordered the part, will call me to install when it arrives, will let you know if it solves the problem, which I expect it will!
