Re: Fan blower problem
It is the resistor located between the blowermotor and the wiring . Usually located under the dash on the blower housing or in between the radiator and the blower motor. In the wiring. It is a small gadget. Not a resistor as in TV resistor. It controls the speed of the blower fan. Replace that. If it does not work replace the blower motor. But I am fairly confidemt that could be the problem.

Generally if the a/c works fine at highway speeds but kicks out or slowly begins to blow warmer and warmer air as the vehicle is driven at slow speeds or is stopped the a/c condensor cooling fan is usually at fault. At highway speeds there is enough air being forced through the radiator, condenser, and oil coolers to keep everything working and cool but when the vehicle is moving slowly or is parked the electric and mechanical cooling fans have to be working to pull enough air through to keep things working. If the cooling fan isn't working or can't pull enough air through the a/c condensor the system will kick out once the internal pressure reaches a certain point. Once the vehicle is moving again the system can get rid of the heat that it has gathered from the passenger cabin, the pressure drops back to normal and the system cools again. I would start by looking for a blown cooling fan fuse in the fuse panel under the hood. Usually they are 25 amps or larger and run only the cooling fan.
the blower motor has no affect on the AC system, start the engine and turn on AC and watch the AC compressor to see if clutch engages,if it doesn't the system isn't full,if you are correct the clutch should be engaged and should quit when you change heater speeds,
First check the fuse for the heater/ac fan. If the fuse is OK, you probably need a new blower motor. If the fuse is blown, replace it. If it blows again, you could have short in the heat/ac control computer, or the blower motor may still be bad. In this vehicle, the blower motor is probably less expensive to replace than the controller, and you can test the blower once it is disconnected by applying battery voltage to it (observe correct polarity). If it does not move when jumped directly to the battery, it is almost certainly bad.
Sounds like a blower motor not turning the blower. Could be elecrical. Check fuses that control the blower motor or blower motor relay. If these seem to be okay, locate the blower motor relay and try replacing it with a known working relay of the same style. If the A/C begins to blow, then you need a new relay. If not, you'll be looking into the blower motor or fan. Make sure your cooling fans function while your A/C is engaged.
