When does it go off (the fan). I assume it does, sooner or later, go off? Some blowers (high-end vehicles) stay on a little longer to clear moisture, but if this just started (hasn't happened since day one) then I would assume it is a short (pray it isn't) or the blower cutoff relay/blower motor relay. If neither relay is available for that car, it could be built-in to the motor. Then, try to unhook the motor and put a tester on the connection plug going into the motor and see if you can get power with the car on, and watch it disappear once the car is turned off, that indicates it is the motor or the resistor atop the motor.

Can someone tell me what fuse to pull-in my 2006 Hummer H2 SUT? I now need to pull the fuse and try to carefully extract the (all glass) portion of the # 194 bulb-which broke. Bummer.

Fuse rating are normally on the inside lid of the box cover. Fuses are colour coded. You wouldn't normally pull a fuse to replace a bulb. Power off, lights off, use tweezers to remove a broken capless bulb.

I am trying to install an after market tachometer in my 2003 Hummer H2 - the instructions indicate tying one wire into the ignition switch? Thanks, Larry D'Angelo

Any power source that is switched will work, so use a test light to find a fuse that is only powered when the key is turned to run.

There are fuses located on thedrivers side when you open the front door. There is a panel that pops off near the door pillar. The fuse diagram is loacted on the panel. Secondly there are fuses located under the hood. There is a black plastic fuse box, with fuses and relays. also there was a recall for the wiper motor on some of the H2. I hope this helps.
