Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.

SOURCE: heater blower switch only works on high

I'd replace blower resistor, usually found under hood on firewall on passenger side, or on duct work, inside under dash on passenger side,close to blower motor.

You haver a small leak in the seal in the slave cylinder, I believe they sell and aftermarket kit to put ther slave cylinder on the outside, a better system. I believe they changed the design in the early 90's

2001 Jeep Wrangler heater blower stopped working


Yes I would go with the switch, BUT, does it have a resistor bank? That is, how does it reduce the speed? Many systems use resistors to lower the speed. Burnt or bad connections can cause this as well.
You can test the blower motor by connecting direct power from a source like the cigarette lighter if you are handy.
Most of the time the lower speeds konk out but the high speed continues to work this is the resistor bank that goes out.

I have a 1999 Jeep Wrangler and the heater fan stopped working for all the fan speeds. The fuses are fine. How do you know if it is the blower resistor or the blower motor?


If you bypass the resistor pack and connect the motor directly to the fused 12v supply then the fan should run at maximum speed. If so, it's the resistor pack that's blown: a very common fault on a huge number of makes and models.

No Heat 1988 Jeep wrangler


any time you do not have hot water in the hoses to the in side of the vehicle, your water has quit either due to you having only water in the system and it froze in the winter and you started it . or the propeller just broke of old age. make sure u dont have a check valve in the hoses going to the heater core in side the car. valve would be under the hood somewhere in the duration of one of the two hoses, which is the feed. this should do u good
