Thanks very much. The problem was the fan relay. I checked all suggestions above. After taking it to a shop, they decided it was either relay or temp sensor and changed relay first. The sensor is fine.
 
The main tip-off: when it was overheating, the fans weren't running.... even when AC was turned on. Everything else was operating normally and there were no other inidcators such as cracked blocks, plugged thermonstats etc.

Town and Country overheating by 785j3

96 Town/country with overheating problems when pulling hills in 90 degree plus temp (any gear). New water pump. Radiator full, no leaks. Electric fans functional. Remedy is to pull over and allow the fans to cool off the water temp at idle. Radiator appears to be under-capacitied and incapable of keeping the engine cool. Hard to believe Chrysler didn't do a better job of building an adequate cooling system. Any ideas short of a larger radiator?

I have a 1998, same issue. There was a TSB on this, the dealer should replace the relay at no charge. You can find this information at Dodge.com Good luck, they've replaced mine six, yes, that's 6 times, 2 different Dodge dealerships and one independent mechanic review, in the 2 years that I have had this 1998 Dodge Grand Caravan! The relay keeps keeps shorting out, which overheats the van very, very quickly, last time I had to pay for the wiring plug that the recalled relay shorted out, and yes, you guessed it, my van sits at the Dodge dealership today, waiting, waiting, same problem. The last replacement was Nov. 2006, ten months ago.

Below is the bulletin I found regarding my 1998 Dodge Grand Caravan. I have noticed that the Chrysler Town and Country has many of the same bulletins. Dodge has replaced my relay free of charge several times, but last time they charged me for the electrical plug that the relay burned out. It is now at Dodge again, in the shop, waiting, waiting,...I have had the van for 2 years. The first time it overheated, an independant mechanic replaced the thermastat and that did not stop the overheating. He ran a diagnostic and then he gave me the bulletin, so I went to Dodge dealer #1. In a period of a month or two, I visited then often and got new relays. This is my second trip to Dodge #2 for this since last Nov., wish me luck and I'll wish you luck!

2001 Chrysler Dodge Town & Country Cabin Heat Problem by chaz6

I have a 2001 Chrysler Town & Country LX MiniVan. It has nearly 160,000 miles on it. I live in Michigan where it gets cold and snows. Two weeks ago (end of January), the vehicle began having heating issues...
 
Upon start up, the engine runs fine. The needle on the engine temperature gauage remains at the bottom, at "C" for at least 5 to 10 mins. Then it slow increases to the 1/4 mark. Then within 1 minute it shoots up the the 7/8 mark close to the "H". (The first few times this happened I shut off the vehicle). However, now I found that after another 5 minutes, the needle lowers back down to the "just below the 1/2 way" mark.
 
At the same time, my cabin heat stopped functioning correctly. Related? Perhaps.
 
I can't get any heat in the cabin unless I'm traveling at least 40 mph. Therefore while driving through town, there is not heat. On the highway, I have all the heat I want. However after slowing back down to below 40 mph, the vehicle begins blowing cold air again.
 
Since I take my children to school in the morning, they are freezing the whole way. I don't dare turn on the heat since it only blows cold air, but instead I've given them blankets. After dropping them off, I hit the highway to get to work, and then I'm warm and toasty!
 
Let me know what you think,
 
Chaz

Have you checked the coolant level in the white overflow reservoir? You should see the coolant line at the minimum line, when the engine is cold and between the minimum and maximum line, when engine is warm. Also, look for visual leaks under the hood and on the ground, when the engine is at regular temp. When you are driving at a constant speed, does it over heat or is it just when driving around town?

2005 Grand Caravan - Overheating and Heating Issues by jasonclement

I am having the same problem as the guy with the 2001 T&C. Engine keeps overheating at random times, and the inside heat only seems to work when I am giving the van gas... anyone have any insight on this? Are the two issues related?

Sounds like you are getting an airlock. This may be due simply to low coolant levels, or it could be a water pump issue, or worse. Have you checked the level of your coolant? If it is low, park it on ramps or with nose-uphill, and slowly fill until all bubbles stop emanating from the radiator, then see if it helps.
 
If it is the water pump, the lack of heat and the overheating will be simultaneous even though you are topped off on fluid. Without the water pump circulating the coolant, the heater core will go cold while the stuff in the engine boils (if hot enough!).

I HAVE HAD THE OVERHEATING ISSUES SINCE I HAVE OWNED MY 1998 DODGE GRAND CARAVAN. HERE IS WHAT I HAVE FOUND:
 
THERE IS A TSB ON THESE VEHICLES, HERE IS THE LINK TO LOOK IT UP AS WELL AS RECALLS: http://www-odi.nhtsa.dot.gov/cars/problems/recalls/recallsearch.cfm
SEARCH FOR THE COOLING RELAY BULLETIN ON YOUR TOWN AND COUNTRY MINI-VAN USING THE SEARCH ENGINE PROVIDED BY THE OFFICE OF DEFECTS INVESTIGATION.
 
IN MY 1998 GRAND CARAVAN, THE COOLING RELAY WAS DEFECTIVE, THEY HAVE REPLACED MINE 8 TIMES AT NO CHARGE, THE 9TH TIME, THEY, (CRYSTAL DODGE IN CRYSTAL RIVER, FL), SAID IT IS NOT A "LIFETIME RECALL". I DID FIND OUT THAT THE COOLING RELAY SHORTS OUT DUE TO THE HIGH AMPAGE OF THE FAN MODULE, ONCE I REPLACED THE FAN MODULE, I HAVE HAD NO OVERHEATING, WHICH PRIORLY IT HAD DONE 9 TIMES THAT I WAS AWARE OF.
