Question about Jeep Grand Cherokee

1 Answer

2004 Jeep gand cherokee blowing #20 fuse.

Not an issue with the turn signals or heater, so it has to be the reverse light circuit somewhere. I have tried taking the bulbs out completely, and unplugging the reverse sensor from the tranny, and still blows fuse as soon as car is put into reverse. I have also taken the center console out and unplugged the connecter there, but still blowing fuses (even 30A's) Need some help as this is the girlfriend's car and we can't really afford to take it to a shop.

SOURCE: Fuse keeps blowing on 2004 Jeep Grand Cherokee

You've probably solved your problem by now but if not, you really need to buy a cheap digital multimeter. It will help you in this kind of situation and others.
Connecting it between the output side of the fuse for that circuit and ground can let you start pulling connectors until the low resistance causing the blown fuses goes away.
Experience with this kind of troubleshooting helps so you may be a little uncertain at first.

They can be had at auto-parts stores, Radio Shack, or if you are lucky enough to have a Harbor Freight tool store near you, they often have the things for $3 and while not exactly precision instruments, they are adequate for most anything one can do at home.

SOURCE: alternator fuse blows

Kevin, chances are that when the new alternator was put on. The wires were put too close to something either hot or that it can rub on. If you do not find that this is the problem then return the alternator to the store and have it tested for internal problems. Bad Alternator can do this. Good luck

SOURCE: Fuse keeps blowing on 2004 Jeep Grand Cherokee

Your fan seems to be drawing way too much current, common with fan motors of all kinds when they are going bad. It will still blow, but hot wires and blown fuses in the normal circuit indicate you have an excessive load in the circuit. Fan motors create this condition regularly, but are often ignored since they are "still blowing."

Here's a cheap, easy way to test my theory:
Try a new fuse, the proper amperage, but leave the blower motor unplugged at the blower itself. That will tell you in a few rides if the blower was the culprit. (Which it most likely is.) I bet your #20 fuse will stop blowing and no more smoking pink wires! Hope this helps. Remember, blower motors are cheap, traffic tickets and dash fires are not. The blower motor draw is the logical thing wrong with this picture. Good LUCK! TT

SOURCE: Wiper fuse keeps blowing intermittently.

It looks like the wire circuit for the wiper motor is touching the car body when shaken so the only thing you can do is shake the wires and terminals yourself while engine is running then maybe you can pinpoint where the earthing is.

Why does my turn signal/ hazard light fuse keep blowing out


you have a short in one of the light sockets or a worn wire from the wiring harness. could be the flasher assembly. are the turn signals different bulbs from the brake lights? Does using the brakes blow the fuse? (Rear lights or brake light switch on brake pedal). left or right turn signal blowing the fuse will tell which side has the short. 4 ways only, replace the relay.

Click on the link, check fuse f13--20 amp. Not only check the fuse, check the fuse circuit for voltage, use a test lite, hot all the time.
You have to test when problem is ongoing. The fuse is for brake lamps.
At the moment, I don't know if trouble shooting one system will fix the rest? With multiple issues, I pick one system and trouble shoot.

I have a 2002 jeep grand cherokee and my turn signals stopped working. My hazard lights are working fine. Lights are working also. But im not getting a light on the dash for my turn signals.


I have the same issue. I took the flasher relay out, inspected the pieces for any hairline fractures on the circuit board, nothing it was clean. On my jeep, the turn signals always work in the Spring, Summer, Fall months, but as soon as Winter hits I loose my turn signals. Also, I know it is temperature related because I drive around for a half hour and the signals work again. It is really strange, I think the issue is somewhere in the ground wire, I will be checking that next and will post any new information. Anybody else who has had this issue and correlation I would certainly like to hear about any solutions. Thanks

After checking the fuses I would replace the fuse for the tail lights just to make sure it wasn't a fuse issue and if that doesn't do it I would check the bulbs on both sides to make sure that the bulbs are good.
