My van, a 1998 Grand Caravan 3.8L, was overheating in traffic. Specially when the A/C was on. The check engine light was on. My radiator fan would not turning on. I just replaced my fan relay which I bought from a Dodge dealer for about $80. It is screwed on the van chassi next to the bottom corner of the radiator and below the left head light (driver side). I had to remove the air filter kit to get to it. I pulled the connector off the relay by depressing the little unlocking lever (I don't know what it is called)on the connector...slips off easy...no need special tool but can be tricky. Fan now works and Check Engine light is no longer on. Sorry about your A/C. Good luck!

No!!!! I have replaced that fan relay and it takes about 5 minutes. Drivers side, mounted on the frame (one screw) near the bottom of the radiator. Good luck with your van, I absolutely abhor mine. Without a doubt the biggest lemon I have ever owned. Wouldn't be so bad if Dodge would back their products but they don't (or won't), they are making a fortune on PCM's, BCM'S and TCM'S.

98 DODGE CV FAN SWITCH IS BEHIND THE AIR FILTER AND HAS 4 WIRES. VERY COMMON PROBLEM, SWITCH COSTS AT LOCAL SUPPLIERS ABOUT 19 TO 35 DOLLARS.
SOUNDS AS IF HE IS A TYPICAL MECHANIC $$

I have a 3.3 dodge Caravan, you were absolutely right, the relay was bad. I replaced the thermostat and it still over heated, and the air conditioner was starting to blow humid warm air, I guess the relay effects alot on the car. Great call. Thanks again

Incase any of you Dodge owners come across this problem of fans not turning on and car overheats. Check that fans rotate manually but first pull the negative off battery to prevent fans from turning on. The fans are controlled by a fan relay which is located underneath the Air Filter on the right side of the radiator. Cost is about $20 to 30 dollars to replace yourself. This took care of car overheating.

Need Assistance! 1998 Dodge Grand Caravan-while running ac temperature gauge goes up but vehicle never overheats and ac starts to blow warm air. No service lights at all. Except for the flashing ones on the ac control panels. Fans come on when ac comes on all the time. The van has a fairly new fan relay, temperature switch, thermostat, new radiator,rebuilt transmission,new fuel pump, new starter, new water pump,new tensioner and serpentine belt and now I am broke and never buy a Dodge.

Bought my 1998 Dodge Grand C.V. in 2003 with 100,000 miles on it. No problems until April 2007 when it turned 200,000 miles and by now July 2008 I've replaced A/C compressor, exhaust manifold, belt & tensioner, water pump, starter, brakes & tires, a few minor things and last week the radiator blew a 7 inch crack down the side. I was 1 mile from the Chrysler dealership so after cooling down I got over there by 6:05pm and I had my entire family with me!(wife, pregnant, and 4 children under the age of 8. I refused to leave until they did something about it. The manager put me in a new caravan for 2 days free of charge and took his sweet time repairing the radiator, hoping I'd buy a new C/V. Nope! Thanks for the free ride! Now here's a credit card...give me my mini-van that runs fine still and no payment for years now. If the economy doesn't change the credit card company may have to do a write-off on me because although i work hard, i don't make much and there now raising my pay anytime soon. Oh, they said they replaced the relay switch for the fans and a day after replacing it my a/c blows humid air while parked and the temp gauge shoots up. So I pull out the entire air cleaner assembly to get a better look at the wires and fans and i see the small square you've described and tap it with a wrench, start the car, turn on the a/c and the fans start working perfectly! Unfortunately, I'm in Orlando on vacation and I've had to repeat the process 3 times in the last couple of days. I get it working every time but i can't wait to get back to talk with Chuck the service manager. I'm leaving him a message tonight! i don't like to get taken advantage of especially when I have a family to protect and take care of. Life happens, but we can speak up and make a difference...firmly but nicely. Nobody likes a butthead but the right intentions can get some favor. Good luck people!!!

Do you think the dealership would actually say they've changed it but not? What's you're credit card payment gonna be with all those repairs? Is it definitely the relay switch? I agree...speak up and stand your ground but don't be a butt-head. May God bless you family man.

Hey Shamu! I just saw you! How do you have internet in that freezing water? Thanks for the cool, salty splash! It was refreshing on a hot summer day...I think even dealerships could do corrupt things when no one is looking. i can't be sure because i didn't hide a camera to spy on them but as soon as i get home I'm taking it back and they will fix it and I mean they usually are very apologetic and get it fixed. A hole-in-the-wall mechanic might not get to it so quick.$100 a month is about what I'll pay monthly for now...what's it to ya? After a good cool off, I took about 30 minutes to go through a series of trial and error tests like pulling fuses, jiggling wires, tapping the fans, etc and nothing made the fans come on until i tapped the relay screwed to the frame under the air cleaner mass. So i know it's that little booger!!! And yeah, speak up but don't be a butthead!!! K, see you in November Shamu when it cools off a bit and lines aren't so long...

By the way Shamu...wanna buy a Dodge Caravan? I realize that I'd better buy another used mini-van sometime soon. Any advice on the best min vans? Mine is a 3.3 and gets good gas milage on the highway. I've had a town and country with a 3.8 and it sucked gas all the time but the 3.3 does way better and still has good power. Help if you want...

I have a 98 dodge grand caravan SE and I replaced the radiator fan relay myself about 2 months ago! The check engine soon light came on and van started to overheat today, so I took it up to auto zone to hook it up to there computer, found out it was the same thing again. The rad/fan relay is 60 dollars for this van and don't want to have to keep replacing it, does anyone out there know what could cause this? By the way, I already checked the MAXI Fuse to it and it's fine.

I have a 99 dodge grand caravan with the same issues. It continues to overheat. The engine light had gone on - we got that checked and it said the relay was the issue. So we changed that and it did not help. We now have changed the temp. sensor and the fuse. Still over heats. The fans do work, we hooked them up directly to the battery, they just will not come on. I was told a few times it may be the engine temp sending unit?? Have no idea where or what that is. We have called a few auto stores and no one carries it. Any one know what that is or maybe what else to try?

hi, I just cant belive us people have to go thru this stuff. mine doing the same thing. i took local shop and they said it was the relay fan, so they put that on and didnt work, then temp sending unit, thermo stat, change rad fluid.

now my fans dont work but when you turn on the aircond on and the fans will kick on for less then 10 seconds and then they kick on a few seconds again and that not normal b/c most when they reach hot point they stay on more then 10 seconds. i can get anone to help and autzone just say well it might be a water pump, but it not leaking...

still and the local shop called the dealer and then they said well that why you need to bring in the shop that they have better equip. so then they told him the one code migt be the pcm and that over 300dollars for the part. so now i here debating finding another local shop or be screwed with the high labor cost and take it to the dealer.

after i had my trasmission fluid change from one dealer and the min i took it off the lot then i ended up having to get a rebuild trasmission that cost over 2grand, that why i dont like dealers.

any help apprecaited. it just i have kids and hate to be standed... thanks

Sounds like the same problem I have. I could do an engine out belt service on a Ferrari for less than I've spent on my wife's Grand Caravan in the last 3 years. Chrysler is archaic. List of vehicles I've owned that never game me a hint of trouble (other than some rust)
1. 1978 Honda Accord
2. 1990 Mazda MX-6
3. 2001 Honda CR-V
4. 2002 Jag
I could respect Chrysler if they actually seemed to make an effort to remedy these problem areas year after year. However, it seems they don't give a s---. I find it insulting and very disrespectful to their customers.
