1992 cherokee problems

[kschlei]

HI, I am new to this forum and I have a couple of promblems with my '92 Cherokee:

1. When the wipers are on, the the arms go past the windshield and hit the "body" of the vehicle. Is this a problem with the motor? or the arm assembly.

2. A/C and heater motor only operates on high. The dealer said to replace the reiostat, but I can't find it.

3. The front axle/differentail when I turn left or right makes this horrible noise, sound like a bad diff. Should I replace both sides of the front axle?

Any help would be appreciated, THANKS! Karl

as for the noise, make sure your tires are not rubbing, that is if you have larger tires.
The wipers, when they are parked do they end in normal position or are they angled up? If they are just turn wipers off, remove arm and install in proper location, of just bend them back .

The fan switch I believe is just behind the climate control panel.
