My father's 1998 Dodge Grand Caravan SE radiator fan runs constantly - even with the ignition off. He has to disengage the battery for the fan to quit running - what might be wrong?
View 14 RepliesSo my radiator fans were staying on until my battery died and my car was completely cooled down and off. I was told it was a sticking relay so I replaced it and the fans still won't come on. I unplugged the coolant temp sensor and the fans came on so I know its not the motors or anything.

I also have my CE light on. Hooked up my reader and got the "P1491 Radiator Fan Control Relay" code. I have checked my rad fan fuse and it is okay. My attempt to locate the rad fan relay took me from the rad fan wire to a device that looks like a heat sink. It is located on the vehicle frame between the rad. and front grill. Is this the rad fan relay? If it is I'm not sure how I would replace it. It seems riveted to the frame.
I have a 1998 Plymouth Grand Voyager SE. It has 122000 mi. I just bought it a few months ago and have came across a few minor problems and all have been easy DIY projects (couple of blown fuses, wiper replacement etc..) Recently, I noticed the AC stopped working (it was only tested once when I bought it, but have not used it since)
Where to begin the diagnosis. Is there a fuse connected to the functioning of the AC? I really don't know a whole lot about cars, but I am pretty good at fixing things in general.
I took the van on a road trip and the engine seems like it wants to stall at lights. the idle stays at 500 rpm or so most of the time while at stops. there appears to be no way to adjust the idle and there is no Czech injun light on.. what could the problem be? the engine is a 3.8l
View 4 RepliesI'm about to put a new tailgate on a 98 Dodge Caravan. I got hit in the back and I bought a new back door at the junk yard. It looks pretty easy, but I thought I would touch base here and there are a couple of potentially tricky parts...
Does that wire bundle have a block somewhere that you can plug, or am I going to be splicing them one by one? (I don't have power locks. I have windshield wiper, back door inside light, license plate light, heat wires in the glass.) The other tricky part..changing the lock.
I think that's all.. the bolts and star screws look pretty straightforward. I got it used with 48k miles a couple years ago and I only have 75k now. It was a government car.
I have a 1998 Caravan and the engine cooling fans wont go on. Ive replaced the relay and the temp sensor. When I pull the connector off the temp sensor the fans go on so I know the fans and fuses are fine. For some reason it seems the computer module isnt sending a signal to the relay to turn the fan on. I get the trouble codes P1491(radiator fan relay circuit fault) and P0118(engine coolant temp circuit high input).
I am also having a problem with the air conditioning not working. When I do the self diagnostic test on the A/C the results are that it fails the cool-down test. Why the computer module isn't sending a signal to the relay? Could the A/C problem be causing the cooling fans not to come on?
The battery light came on, alt not charging. I have taken it off twice and had it checked, both times I had it checked it showed good, when I put it back on it charged for a bit and then the light came back on and it showed no charging at the battery. Second time the place checked it they ran the check cycle 4 times in a row to see if it had a problem when the electronics started warming up... still showed all green.
I thought perhaps the wires going to the alt, so I had the wife start the van up and I moved the wires around going to the alt to see if it made the batt light flicker, no joy. (real fun getting your hand back there while the van is running)
The large wire shows batt voltage where it hooks on to the alt, running or not...... the two prong plug that goes into the alt shows no voltage unhooked with the key on, and no voltage plugged in with the key on or running.
I have been told there is a control unit that controls the output of the alternator. I have checked every fuse in the fusebox under the dash and in the engine compartment. Fuseable link on big wire going to the alt should be good as I do get battery voltage to the alt from the battery, correct?
My wife has been driving our 98 Dodge Grand Caravan the last couple of days and while she is driving the Tachometer and Speedometer will drop to 0. This does not affect the performance of the engine or anything else. Runs and drives "perfect" (or at least for its age and mileage). The dash seems to "reset" when she parks and turns off the ignition then restarts it.
View 2 RepliesThe heater fan in the van will only work on full blast and the rear wiper/ ac button lights flash which I had another 98 caravan that I was driving that had the same issue with the flashing lights. What is that all about?
View 2 RepliesJust changed the battery on a '98 Grand Caravan 3.3. In the process of tightening the positive terminal I accidentally touched the wrench to the negative. There was a spark, of course, but otherwise no biggie. However, now the HVAC indicator lights, including the rear wiper, defroster, etc. indicator lights, all blink continuously until about 15 minutes of driving, then they return to normal. I disconnected the battery thinking that I needed to clear the PCM but the blinking always returns. Is this some sort of manual code reading deal? If so there's no mention of it in the Haynes manual.
View 14 RepliesI can usually find what Im looking for with a quick search but I have had no luck with this issue.
View 19 RepliesIt is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.
My 1998 T&C has a problem where the front passenger window keeps falling off the track (caused by hard slamming of the door).
I've gone into the door multiple times to pop the rear-most peg back into the white plastic window track "dog", but it keeps popping out after moderate door slams. Do the black pegs that are glued to the window wear out? (I think they're metal).
I think the plastic track dog is fine, and I make sure the metal clip is fully engaged with the window peg each time I pop it back in. The only reason I can come up with for this problem is that the window peg is worn down and has lost its "edge" and thus the metal clips can no longer retain it. Sound reasonable? Probably need a new window from junkyard correct?
98 dodge caravan 3.3L v6 ..... All lights work including driver's side tail lights. only problem is that when pressing brake pedal, the driver's side brake light does not light up. i changed the bulb and checked the brake light fuse under the hood, but it was fine (as i guessed since the passenger side and middle brake lights work). I took the assembly off and reseated the connector to the tail light assembly, but same issue.
View 2 RepliesMy 1998 Grand Am (2.4L)radiator fan keeps running after I shut the engine off. This is after a short drive of ten minutes. Both times it did it, it was not an unusually hot day and stopped after I started and turned off the engine again. I have owned the car 7 years and it has never done this before.
View 1 RepliesWe just purchased a 2012 Grand Caravan and was wondering where to get a key and program it. I know the key will be an arm and a leg if i get it from the dealer. Is there a tutorial that tells how to program it as well?

View 2 RepliesOn my 2005 3.3L Grand Caravan the ABS light keeping coming on. I inspected the sensors for the front and used my compressor to give them a quick puff of air to get rid of dust. The light went off for about 5 days. Now it is back on.
How does one read ABS codes? If I knew for sure that the problem is a speed sensor and which one I could clean or replace the faulty sensor.
If I clean to sensor are there any special precautions I need to take? As far as I could see they didn't look very dirty.
What am i missing i have a terrible clunk in the front end when i hit bumps. I thought it was the struts and mounting plates so they are new . no change Stabilizer links were tight but i replaced them as well. Everything else seems tight but the noise has not changed with any of the above mentioned repairs.
View 13 RepliesI'm having trouble with my 96' 3.0L, its kind of crazy its intermittent and while driving the engines surges one or twice and then dies... when I try to crank it up again cranks but don't starts if I try again it wont even crank ( no starter winding up ) what I noticed is that is I'm driving when it dies my check engine light disappears for a while and if I connect my OBD 2 reader does not link up with the ECU if I wait a while and I crank it up again its starts and the while cranking up I can hear a bang noise from the engine compartment drives side and then after a couple of minutes dies again...
