i got a 92 xj 4.0 and my blower for the heat and ac just stopped workin when i drove it last night it was fine and when i got in this mornin it dont work the fuse is good any suggestions?

 

probably works on high, did you check that?

 

yea it dont work on anything

 

hmph. run a lead directly to the blower motor and see if it works.

 

where is the blower at in a cherokee

 

It's under the hood, on the passenger side, hanging through a hole in the firewall. On my 89, it's under a metal plate that holds a coolant tank. On a friend's 94, it's underneath the washer fluid reservoir, both of which are easy to remove. You can follow the only harness that comes from the motor to a connector that you can disconnect. Throw some wires onto the battery terminals, and connect them to the terminals in the socket going to the motor. If the motor fires up, it could be your blower motor resistor gone bad. On said mentioned friend's truck, it turned out to be a dying motor that killed his resistor. On my truck, the fuse was good, but had melted the socket. Good luck!

 

what the **** now it works it didnt work on my drive to work it didnt work drivein to lunch but on the drive home it worked fine hows that work?

 

My buddy's was intermittent like that. If it stops working again, turn the heat on full blast and tap the motor a few times with a hammer. If it kicks on, then your motor is going bad.

 

Bad relay, loose ground

 

it stopped workin again so i tyurned it on and hit it wit a scew driver and it ran fine guess i need a blower. thanks guys
