Jeep - Electrical-wiring - Wrangler :: Wipers Don't Always Work / Quit Without Warning
Sep 11, 2011
I have a 1999 Jeep Wrangler Sport 4.0L with a kind of serious problem. My wipers dont always work. Sometimes they work fine, sometimes they work fine to start with and then quit without warning, other times the only way to get them to turn on is to turn them on high and then go to the speed that I want to use. It has the intermittent option but I am not yet convinced that that has anything to do with my problem. They will quit working some of the time while using the delay but they also quit on low sometimes. I have been through and checked all of the plugs, and even went as far as to grease them up so I know they are making good connections. I'm at a loss, I would think if it were the motor or the switch it would just go out all together. And if it were a broken wire, wouldn't it come on and go off if I hit a bump in the road? They shut off on smooth roads so bumpy or smooth does not matter.

While driving I turned on my headlights and my car became possessed. My warning lights started to flicker on and off, my car was dinging out of control. The speedometer, gas, and RPM gauge went to zero. My brights light would not come on. My dinging for the lights being left on, or the key being left in the ignition, after the car is parked, and the door is open, will not go on either. I turned my lights off and all was well. Turned them on again and the same thing happened.
Now, the following day, it is doing this periodically every couple of minutes while I'm driving, whether the lights are on or not. My radio and head lights work fine. I checked all my fuses and they all seem to be AOK. I disconnected my car battery and reconnected it to see if it would reset and it still did the same thing. One other strange occurrence. The last month or so while I've been driving my battery light came on for a few minutes. I had the battery checked and it is not bad. Then last week my gas-cap warning started to randomly appear. I changed my gas cap, and guess what.....it still came on, at random.

My Jeep Wrangler periodically has the wiper go on when using the turn signals.

I am having a “Check Engine” light problem on a stock 06, 4 cylinder Jeep Wrangler with manual transmission. A local highly regarded independent mechanic has had it in his shop 3 or 4 times for more than a day each time. On the first visit he replaced a purge solenoid valve and reset the light. It stayed off for more than 400 miles and then relit. He went over it and checked the wires and connections and reset the light. Again it stayed off for some time and then relit. He has checked the Jeep site.
After the last visit he suggested I drive it and see if it would reset itself as it had been doing in the past. It did reset itself twice but it only stayed off for 10 miles the first time and 2 the second. The code indicates an electrical problem and he is now planning to drop the fuel tank and check the wires and sensors there. The next step may be an ECM transplant. This is only an emission system problem and the mechanic says it is OK to drive. We do not have emission inspections here. How important is it to fix the problem?

I have a '98 Jeep Wrangler with various problems, but the most recent one has to do with the turn signals. When I intentionally use them, they seem to be working, but when I haven't signaled I still hear the ticking sound, only double-time. The sound is normal when I turn the signal on, and only stops when I apply the brake. I recently took the top off and left the Jeep uncovered in a couple of storms. Could this have caused electrical damage? Also, the left turn signal has required some finesse for as long as I've had the car--I've always needed to fiddle with it to get it to turn on--so I'm wondering if it's a wire connection that has deteriorated over time.

Wipers work in all modes, but won't shut off. I was told there should be a shut off in the wiper motor that's not working. Would I be able to splice in a shut off switch, where is the best place?

I have a 99 f450 and the wipers work when not on. it's this an electrical issue or a bad wiper motor.

One of my outside roof lights quit. I replaced the bulb and it's still down. These are all on one fuse right? 2001 Super Duty is the year.

I *think* I'm having trouble with the alternator on my 2002 Navigator with the 5.4L DOHC engine.
A year ago in Feb 2014 the alternator quit charging. I thought the headlights were a little dim, but when the radio turned itself off and then the heater fan did the same, I noticed that the alt light was on. Then the engine shut down about 1.5 miles from home.
I'd heard of war stories about rebuilt alternators so I sprang for a brandy new one. I also got a voltmeter that fits in the cigarette lighter so I can monitor the system voltage. All seemed good and the new alternator put out 14.2 to 14.5 volts. Except that the battery never seems to be fully charged. If I check the battery voltage with the engine off it typically reads 11.9 to 12.2 volts. I had Interstate Batteries check the battery. They thought it was okay, but offered to put a new battery in to keep me happy.
Six months and 8,000 miles later I'm up in Ontario back country (on vacation - no tools in the truck) and I notice the engine idles at 900 RPM instead of the usual 650 +/- RPM. Oh-oh, I also notice the volt meter is reading 11.9 volts and drops a tenth about every 10 miles.
Found a shop that was open and they installed a rebuilt alternator and it was putting out 14.2 to 14.5 volts. All was good (except for my wallet!).
Now, here we are six months and 5,000 miles later and the rebuilt alternator is struggling to put out 12.5 volts this afternoon. At a steady 50 MPH with the cruise Control on, the radio, and the heater fan on low, the voltage is bouncing between 12.2 volts and 12.7 volts.
Now to my questions:
1. Shouldn't an alternator put out 14.2 to 14.5 volts all the time? Not just when the alternator is new?
And
2. Is there anything on my truck that could be killing these alternators? Or am I just unlucky in the alternator lottery?

I have an 03 F350 Lariat, the overhead console display quit working awhile back (about 18 months ago) and so far my only option is to buy a new one from Ford. I have looked online, on ebay, local wreckers and have come up with nothing. I have come close a few times but the wrecks didn't have a sunroof so the display is different. I searched and found ways to fix the resistors but mine do not seem to have the poor solder problem that some do. Where I can find a replacement display?

I drive a 2004 Ford Ranger. When I use the remote to unlock my truck, there is a grinding electrical sound, and the driver side door does not unlock. The passenger side does, though. Also, when I try to use my key to unlock the door, the driver's side door will not unlock with the key. I can open the driver's side door from the inside by using the handle, but the electric lock button will not unlock the door. It seems like the piece that pops up when the truck is unlocked has a hard time raising to unlock the door. Neither my boyfriend nor I can figure out what the problem is. I find that when I take my truck in for any problem, people at the dealership try to take advantage of the fact that I'm female and don't know much about cars. Need to know what is going on before I take it in anywhere to get fixed.

I recently changed out the power boost canister for the brakes on a 1990 f-150 2wd. It was successful but now i have no cruise control. I double checked my plugs, all good. I checked my brake lights, all good. brake pedal seems fine and completely raised when not in use. i looked for a fuse and can't find it for that system, seems odd. it's not in fuse jct under dash, can't find a fuse jct under hood, seems odd also. No check engine light has lit.

1997 Ford Expedition 4x4
When I push the switch for the drivers window I can hear the relay in the fuse block make a click but window doesn't move. If I push the switch for any other window (on the drivers door or any other door) no click at the relay and no window movement. I've swapped the relay with other relays in the fuse block but nothing changed.
I've tested the driver side window motor by running 12 volts directly and the motor works fine. When I press the PDL switch I hear a buzzing sound coming from the passenger floor area behind the glove box but the locks do not go up or down. I started the truck and when I put it in gear I can hear the PW relay in the fuse block clicking repeatedly. Put the truck in Park & the clicking stops.
I was told (on another forum) that the problem is most likely my GEM module. Bought a used 1 on eBay and installed it today but nothing changed.

The problem is that my headlights on my 1996 Cherokee Jeep XJ switch off unexpectedly. I can get them to come back on for extended periods by fiddling with the control knob in certain ways. This is the kind where you pull out of the knob to turn the lights on, and can rotate the knob to brighten or dim the dash.
If I pull a bit harder on the knob, the lights come on; if I twist this way just so, then off they go; that sort of thing. The fuses are fine and the contacts in the fuse box are clean. High beams work great no matter what (these are controlled from the steering column). I think the problem is at the control knob.
Now, how can I keep my headlights on when I turn them on every time without having to fight the gremlins? I think my next move is to remove the bezels and so on as best I can and get in there with some proper contact cleaner to see it's just built up gunk causing havoc. If that fails, or if that's a bad idea, what's next?

My wife drives a 2013 jeep patriot with less than 20k miles on it. The turn signals began behaving eccentrically (beeps at strange intervals, and the right turn signal flashing twice as fast most of the time). We figured out that the right rear brake/turn light was out, so I replaced the bulb. That solved the problems, but on the way I noticed that the widget that the bulb plugs into looks just scorched (see pics). I don't have enough experience with these vehicles to know if this is normal, or if this means more trouble to come.

Problem 1: Headlight switch occasionally needs to be jiggled to get headlights on.
Problem 2: Wipers only work in the "spray and wipe" mode.
My Solution: Removed dash, installed new switches, replaced dash.Result: Now the right headlight does not come on at all. Wipers STILL only work in the "Spray and wipe" mode.
Question: Where do I go from here?

85 f150. My driver side brake light and turn signal in the back quit working. The tail light works tho which is a different filament. The bulb is good and I changed the flasher relay...the circle thing in the fuse panel. Everything else works just fine. looking for a starting point.

I have a 95 Jeep Cherokee that has a strange electrical problem. When I first turn the car on after it has been sitting for several hours, the following accessories do not work:- Air conditioner/Ventilation- Wipers- Cigarette lighter
There are two really odd things going on here: The first is that the radio will not work if any of the above three things are turned on, but it WILL work if they are all turned off. For example, with the wipers and AC off, and cell charger unplugged from the lighter, the radio will turn on. As soon as I plug the charger in, or turn on the wipers or AC, the radio goes off. None of these accessories actually turn on, but simply being putting them in the "on" position kills the radio until they are switched off.
The second weird thing is that after a few minutes of driving, everything will return to working as normal - radio, AC, lighter, etc. They continue to work until the next time the car has been sitting for several hours, at which point the same problem repeats.
FYI, I recently replaced the alternator to address an unrelated issue, but it did not make a difference with this one.
I searched the car talk forums for similar issues, but did not have any luck - while it does look like there are some other Chrysler vehicles that have electrical problems, I couldn't find anything dealing with an intermittent problem.

1998 Jeep Cherokee sport ... My mechanic tells me that my #1 fuel injector is always spraying and that that is why the jeep runs rough. This is after he already told me that my injectors were clogged and needed to be replaced (which he did). When the car is idling for a while, the exhaust really begins to smell like gas, so this seems to make some sense to me, unlike his previous diagnosis. But now he is telling me that I need to replace the computer to fix this problem.
