Caravan/Voyager :: 1998 - Engine Cooling Fans Won't Go On
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?
Caravan/Voyager :: 1998 SE - Radiator Fan Running Constantly
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?

Vehicle: 2003 Dodge Grand Caravan 3.3 Litre
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.

View 6 RepliesCaravan/Voyager :: 1998 - Battery Light Comes On - Not Charging
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?
Caravan/Voyager :: 2003 - New Battery Goes Dead Overnight
I've tried putting new batteries in my mini van and the battery goes dead after a day or 2. I've had it to the dealer before and they said it's a bad battery. which clearly it's not. I had a meter between the grounds on the battery and pulled all fuses under the hood and no change. I'm a quadriplegic and it's a nightmare when I go out with my aid to go to a doctors appointment and my van is dead. I don't have any money for the dealer again. I don't think the chrysler dealer even looked at it and took advantage of my situation. Its a 2003 Town country with only 29,000 miles. could it be the alternator drawing power when the car is off?
View 1 RepliesTouareg :: Radiator Fans Stays On After Ignition Shut Off - Kills Battery
Believe an engine temperature sensor is bad. I took it in to get a code read, and they said it could be either temp sensor or fan switch, but didn't know which one without newer software.
Codes are
19537 - Engine Temperate too Low
P3081 - 008 - Implausible Signal
I've checked the fuse legend to see if there is a fuse I can pull, but none of them marked fan seem to kill it after the car is off, so that I can save some battery power.
I believe that I have narrowed it down to the engine coolant temperature sensor. What is the level of job this is to replace? From a parts location manual, it looks like it is in the Thermostat housing, but I'm not sure where that is.
Caravan/Voyager :: 2011 Battery Light On When Driving On The Intertsate
I am about 600 miles from home and when I was driving on the intertsate the battery light came on. I am in northern Maine where there are long stretches of nothing. I checked to make sure the belt was on and it runs fine. When I got to civilization I shut it off and it started and the light went out. Now I don't know if I should trust it or try and get to a dealer 70 miles away?

Working on a 2001 caravan. Been sitting for about 6 months with no battery installed. decided to work on it. Got a new battery, and when I connected it the alarm went off. I dont have panic button for it so I unhooked the bat.
I think I hooked the bat back up with the thicker gray key in the ignition. I think that is the key with the chip.
The alarm did not sound but the engine will not crank, seems like it it in some security mode blocking start up. I tried cycling the key in the driver door but that did not work.
Caravan/Voyager :: 1998 - Flashing HVAC Lights After New Battery
Just 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 RepliesDodge - Caravan - Relay - Fans - Radiators :: 2000 - Cooling Fan Won't Turn On?
I have a 2000 Dodge Grand Caravan that has 195,000 miles. My radiator fan won't turn on and I'm stumped! The issue presented itself with a check engine light and the radiator cooling fan not turning on. The trouble code indicated the cooling fan relay was faulty. In all cases below, I tested the radiator fan by turning on the air conditioning (thus forcing the cooling fans to run) and also for it to come up to a high temperature coming close to the danger zone.
1. Fuse - first tested the fuse and it was OK. Had to start with simple things first.
2. Cooling fan relay - I replaced the relay which has a reputation for failing on the Dodge. Still the fan did not kick in.
3. Cooling fans - tested the cooling fans and the motor was seized. Replaced the cooling fans and tested them by jumping them. The cooling fans still do not turn on. There is no voltage leaving the cooling fan relay and coming into the cooling fan harness.
4. Wiring - tested the wiring between the relay and the fans. They checked out OK (good continuity and resistance check). There is no voltage leaving the cooling fan relay. Now it's getting more complicated... I unplugged the wiring harness from the ECM and tested the wiring between the ECM and the cooling fan relay. A-OK.
5. ECM - it is unclear how to check the ECM for functionality of the cooling fan.
There are 3 wires (supply, ground, and switch wire?) The supply voltage and ground is good, but I don't know what voltage the switch wire should be. I've read that it is pulse width modulated so I can't measure this with a simple voltmeter. I've also read that the switch wire goes to ground thus triggering the relay. I don't know which is correct. Several mechanics I talked to were skeptical that the issue is with the ECM, they knew of very few instances of this being the culprit. I even replaced the new cooling fan relay with another new cooling fan relay on the off chance that the replacement was faulty. Did I miss something in my logic and diagnostics? I've resorted to wiring a switch directly to the cooling fans and toggling them on and off.
Caravan/Voyager :: 2001 - Is There A Reset Function To Clear Code Disconnecting Battery
I bought some long beams at the local lumber yard. So drove home with the rear cargo door open. The ABS light went on brakes were pulsing mildly and making an odd sound. I cant see why the rear cargo door would have any connection with the ABS system so I assume that's a coincidence.I took the van to the local car store they scanned the code. It scanned code 4 indicating the passenger front sensor. I replaced the sensor but the ABS light is still on. Is there a reset function to clear the code disconnecting the battery didn't work? Or am I looking at another component failure?
View 2 RepliesCaravan/Voyager :: 2000 3.3L Won't Start After Transmission Replacement
I just replaced the transmission in my 2000 3.3L Grand Voyager and now it won't start. It started fine when I drove it into the shop. The battery is good, the cables are ok. The starter worked good up to this point. I checked all the connections to make sure they are tight. I replaced the transmission because reverse went out.
When I turn on the key, the shift letters (PND32) appear on the instrument panel, but the little circle that shows what gear it is in does not appear. When you turn the key to the run position, the circle should be around the P to show it is in park.
When I turn the key to start, nothing happens. No clicks or anything. The next thing I am going to do is see if there is power to the starter when the key is in the start position. Where to start looking?
Camry :: 2000 Vehicle Overheating - Radiator Fans Kick In And Then Temperature Goes Down
My Camry seems to be overheating. When I'm driving the gauge maintains and reads 6/10, when the engine is idling, it goes upto 8/10, radiator fans kick in and then temperature goes down to 6/10 and keeps cycling over a period of 5 mins.
It's got 100K miles, water pump has not been replaced yet.
I checked the hose temperature; top hose 210 F, bottom hose 192, fans kick in when top hose is around 215 F.
I checked the engine temperature where the sender is installed and it was reading 205 F. Coolant level is OK. I burped the system. Previous owner told me, he had thermostat replaced by dealer.
Caravan/Voyager :: 2000 - RPMs Will Jump Up 400 And Go Back While Driving
My wife has a 2000 t&c with 150k on it its a fwd with 3.8 and about a month ago while driving we noticed the rpms will jump up 400 and go back, with cruise control on or off being held at a consistent speed. and about for days ago it started shifting late. Still has all gears fluid looks o.k. and is full no check engine light .
I am hearing transmission solenoid, tps sensor, input sensor, output sensor, tcm, iac, map, or egr are all possibilities or a rebuild . Or simple as a flush.. tonight i went out n started it it idles around 800 tried to hold it at 1200 and it would for a second and drop back to 800 with accelerator being slightly held. Not sure if related. Just observed it..

It is a 2000 with the flex fuel 3.3L 4 speed auto.When this happens the spedo will go from 55mph to 40 instantly while keeping a steady speed and it feels like the tranny is going to rip right out. This will happen every 5 to 10 min but go back to normal driving after 3 sec and has not popped any codes. It runs like a top and all fluids are at the correct levels. I have to commute 50 miles a day to work so i really need to figure this out!!!
