Question about 2000 Jeep Cherokee
Posted by Anonymous on
the fan relay may have went bad...if the fan doesnt come on the compressor will shut down because of excessive pressure...has he used a test light to check all the fuses under the hood and inside... pay particular attention to fuse 10 in the inside fuse box...if there is no power at all to that fuse it may be in the ignition switch

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.

Do you have an alarm on this? If you do, that is most likely the problem. There seems to be a problem with the alarms. You may want to have a new key made just in case. Sometimes the keys are magnetically charged and after time, it wears off.

First, make sure you can turn the engine by hand. If you can't then the starter can't turn it either. Have someone else turn the key and look for the source of the click...may be a relay. Go over the starting circuit with a volt meter. Check for power at the starter main terminal and then with the key turned to "start" check for power at the trigger terminal on the starter. Check battery voltage and check relay operation.
You have a neutral safety switch on the transmission if its an automatic and a clutch switch if it's a stick. Check them as well. Make sure battery grounding on fender and block are also clean and secure.

Testimonial: "Will try! Thanks!"
Before blaming the starter make sure the battery is fully charged. It should be around 13V.
Starter circuits for the most part operates in the following way. Turning the ignition key supplies power to a relay situated in the engine compartment which in turn activates the solenoid on the starter which powers the starter itself.
Make sure your vehicle is in Neutral(Manual gearbox) or Park(Auto box) Locate the starter motor. On the starter there is another cylinder like object called the solenoid. There is a thick red wire running from the battery connected to this. There is also a much thinner wire which activates the solenoid. To test the starter run a wire from the + on the battery to where the thin wire connects on the solenoid. (ignition must be off) This should activate the starter and turn the engine. If nothing happens the starter is probably at fault. Before removing the starter make sure that the engine is properly earthed as this could also give problems.
If the starter does kick in the problem is further "upstream" Most probable cause would be the relay. If you can locate it, replace since it is relatively cheap.
Starter repair is best left to the experts. Get a quote for a new starter before you have the old one repaired. You'd be surprised at how many times it turns out that replacement costs the same as repair.
Let us know if you've solved the problem.
