Hey Guys...
The blower in the YJ decided it wanted to quit yesterday and it's frikin cold.
I checked all the fuses, metered and good to go.
Is there a inheirant problem with the switch or is the switch serviceable?
-
Is it completely off, or is it only blowing on high?

There are resisters that are known to go. from what i'm told they are easily serviceable.

run a fuse wire right to the motor. if it runs your good till you replace the resitor pack. if the motor dont turn then get a new one or dress realy warm. take the doors off for good measure

Made a world of difference in my old YJ.

The old Blazer heater motor swap , yes , a great upgrade to 80's YJ's . Later YJ's have got a larger heater motor , the early motor has a single orange wire , the later motor is a two wire. If you have a two wire it is the larger heater motor.

My YJ was a 95, and I still had to grind the opening to fit the newer blower. Not a lot if I remember, but some. Gearhead is more than likely correct. 8)

My 88 YJ has the heater motor from a 93 YJ , the opening had to be enlarged to get it to fit .
