help!!! 91 xj blower not working at all. heat, vent, or a/c. a/c however hasn't worked since i've own it. all fuses check out, and followed all the vacuum lines i can see under the hood. went wheelin' cauple weeks ago, could i have knocked anything loose? any ideas?

 

Did you check the connection at the blower for power,I would do that first to see if it is the blower or something else.

 

disco'd the connection at the blower motor, and ran jumper from batt. turned on at full blast. so the blower motor must be ok. right?

 

You will need to check the switch and see if there is power to it,may take a bit, you will need to access it. did you check for power from the switch at the blower. does your fan run at all at any speed?

 

currently does not blow at all but at freeway speeds i feel some coming from the outside air. checked at connection by blower and seems low voltage on the meter, where is the switch?

 

your blower switch is the one you use for the fan on the climate control,turn it on and see what the voltage is at the fan,it should varie depending on if you are in high or low.
