Question about 1993 Jeep Grand Cherokee
The a/c-heater fan only runs at top speed on my 93 Grand Cherokee Limited. It has auto climate. The only way I can kill the fan is to pop the fuse in the box under the hood on the passenger side fender well. This happened about 2 years ago, but after about a year, when I put the fuse back in the problem went away and worked all last summer. Its doing it again this summer. There's no relay to my knowlege. I just wonder if its the computer flaking out. I appreciate any light you can shed on this problem
You need to check the resister that is in the circuit, it should be accessible from the passenger side floor. I don't think it cost alot of money to get one, if it is good or you replace it and have the same problem the system requires a trip to the shop as the computer control is not something you can go at to fix..chances are it is this resister though.
It is white ceramic type rectangle in shape,
NOTE...remove the battery negative cable before getting in there to mess with it, there are airbag things you don't want to disturb while working in the area, let the car sit for about 5 minutes before getting busy.
