Question about 2005 Jeep Grand Cherokee
On a 2005 Jeep Grand Cherokee, when turning on the heater or air, the fan speed will only work on high.
Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

Hi, the likely problem is the switch. To access the switch, first unscrew and remove the trim plate from the instrument panel. This will expose the screws to the climate control panel. Your panel may look different than the picture. The exact procedure from autozone.com is pasted below. Once you have the panel out, the switch can be removed from the panel and tested. Use an ohmmeter connected between the switch terminals that would connect to the dark green and black wires. With the switch on high, the resistance should be zero. If not, replace the switch. Please let me know if you have questions, and thanks for using FixYa.
