Ac/ heater fan does not work on high
Hi I'm new here, please bare with me... I have a 2003 grand Cherokee Laredo and my Ac/ Heater fan has quit working on the high position? Is it the blower motor, resistor or the control panel switch? Please help

Old fart with a wrench
It could be the resistor harness plug. Sometimes they overheat and melt. That's usually caused by the resistor or blower motor drawing too many amps. This is on the bottom of the blower motor housing under the glove box. No need to remove the glove box on your model.

I changed the resistor in mine a few weeks ago, I looked on the forums and then googled it and found there are a couple of different types, I removed mine to see the shape , about 5 minutes work, matched it on a pic on ebay, ordered it, it turned up the next day !, fitted and all working fine. Best of luck
