How do you replace the alternator on a 1993 Jeep Grand Cherokee?
you first uplug the battery. there should be some wires on the alt, disconect the with a small wrench or plyers, then take off the belt but remember hoe it goes, then there should be two or three bolts that hold it on from there it is a easy process. After you take the old one off just reverse the whole prosess. Upon inspection of said vehicle it has come to my attention that removing the battery would be a complete waste of time and energy. - MSBILBY
If the clock keeps resetting in a 1993 Jeep Grand Cherokee Limited, the problem is probably with the battery. It is quite possible that the battery is going dead after the vehicle is parked, leaving just enough life in it to restart the car. It can also be an alternator problem causing the battery to be drained.
Correction; that should read "Idle speed motor" I thought this translated to an important question I didn't see here: "How do you replace a speedometer on a Jeep Grand Cherokee?" Mine, in my 1993 Grand Cherokee, has not worked properly for two years and a speedometer shop tried but couldn't fix it. I've been using my Tachometer to estimate MPH. Apologies to the original poster if the correction is yours. And sorry to everyone else…
