One problem related to wiper has been reported for the 1997 Jeep Grand Cherokee. The most recently reported issues are listed below.
Is it common for the blower motor resistor control module to get hot when in use. The blower motor stop working, and I thought it was the resistor that has gone bad, br testing the continuity still ok, plugs, wires ok. But this was what I did. I directly hooked the blower motor to the battery and it kicked off, I then reconnected the plug . . . . To the blower motor back (the resistor module still plugged in) and turn on the a/c again. It came on alright at different speeds, but the unit (resistor) became so hot to touch.
