Hi Speed A/C Blower Only For Jeep Cherokee
Q: Suddenly, Air condition will only work on the HI setting on my 1995 Jeep Grand Cherokee. If set to any other setting, no air will blow out. This sounds like an electrical problem but I’m not sure. Any ideas?
A: A very common problem.Your Jeep may be in need of a blower resistor. When you turn the blower speed control you’re directing electricity though different paths, all of which go to the blower motor. When you select low speed through mid speed you are really directing the electricity through a part called a resistor block. The resistor block has different resistors that control the amount of electricity that goes to the blower motor. But why only high speed? When the blower speed selected is high the resistor block is by-passed and full electrical power is directed straight to the blower motor. In most cases all that is needed is a new blower resistor block to return blower speed control.
