What is wrong Cherokee 90 all of a sudden your windshield wipers radio air blower cigarette lighter and turn signal stop working you have checked the fuse box and all the corresponding fuse are good?

Answer 1

In my case it was the ignition switch. They overheat and carbonize the connectors so that eventually the switch "burns" out and can even lock up and never works again, as it did in my case I don't have an answer for this problem, but I am experiencing this very same problem to the letter. I will add some troubleshooting steps which have not helped, so that noone makes the same mistakeS: * Replaced four relays under the hood ($41) * Replaced starter relay ($54) * Replaced turn signal module ($2) * Replace emergency flasher module ($6) Other troubleshooting discoveries: * Power coming from the engine side the wiring seems to be alright * For every item listed in the original question above, the fuse box was dead (no power) when probed with a test light and the ignition was on. The ACC fuse contact was also dead. * All of the other fuse sockets of the unaffected systems were hot (had power going to them) NOTE: A portion of the fuse box seems to not have power, due to either a bad hot lead, or a bad ground. Which ever is the case, it appears that section of the fuse box is on a totally different electrical circuit from the working side of the fuse box. My next step is to find a good wiring diagram, pull the fuse box, and start tracing bad connections, burnt wires, and anything else I can find. If this helps anyone to track down the problem...PLEASE...Share! Thanks. :o) Have your battery tested - it is most likely a battery-related problem even though it has enough charge to start. I had the same problem; replaced the battery and all is well. Have you checked the fusable links?? - Look where your posative cable goes to. The first stop is a junction block that has many smaller wires coming from it. Each of these wires are for your sub-system voltage feeds. They protect the circuits at the point where they connect to the junction block, it act the same as a fuse, but it is designed to handle much higher currents than a fuse. You can buy the appropriate load fusable link to replace the one that has gone bad, just splice it back into the harness and all will be well again.
