2000 Jeep Grand Cherokee. AC Blower acting strange.

SOURCE: AC Cold air but no volumne of air flow

Check your resister pack, if the air is still cold then the freon is being moved by your compressor and passing through your orfice tube fine so there is the right amount. DO NOT open the system unless you have to, each time it is open they sugggest a dryer/reciecver replacement. The resister pack is a small block about the size of a palm of a hand. It contians a set of coils which conduct electricity at different rates based on that rate <the amount of voltage> your a/c fan will blow that speed. For example high= no resistance, low= 3 reiester if you have 4 settings

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.

SOURCE: ac blower won't work. Resistor has been replaced 3 times. I think it is the problem now. Is it easy to replace? Where is it?

Blower motor resistors are found on the pasenger side ducts near the blower motor. It should have three wires going to it.

hello, this sounds like a bad blower motor resistor!! its cheap and easy to change..if you need more info on locations let me know,, good luck.....marty

I'd check the relay and the resistor ...don't have a location for yours but the resistor is always installed into the heater box so it stays cool. you can usually follow the wiring back to the relay as it's generally nearby. Resistor looks like a piece of circuit board material with several wires connected to it with two screws holding it to the heater box so it sits flush except for the wires. It has several coils inside...any that are broken have failed.
