my 99 caravan overheated last night. when we checked on it today it seemed the cap was bad so we replaced it. when driving with a/c on the van overheats. i checked on the fans thay do not comeon anytime a/c on or off . what can i do to check this out ?? whith out spending alot of money ? just had to spend 1500 on a/c last week

 

Start by checking out the cooling fans. Disconnect harness to fans. Start engine and turn on A/C. Check for power at connector. See which terminal is + and which is -. If you're getting power at the connector, then try hot wiring the fans by supplying battery voltage to the fan connector. But make sure you follow the correct polarity. If the fans don't run, it's a motor problem. If you're not getting power at the connector, check at the fan relays for power. Get back to us with the results.

 

fan relay is toast chrysler put out a recall for some of them give me the last 8 of the vin and I will check for ya or call a dealer and ask them to run the vin and see if your van is on that list.

 

if its not the fan relay.. check fusable links.. take out battery.. remove battery try.. fusable links for cooling fans are under there.. if they are shot.. replace them .. make sure to follow instructions on how to do it properly..

 

there are no fuse links in a NS van u must be thinking of old AS bodys
only one 40 amp fuse in the PDC is for the fans.

 

ahhh yea.. my fault.. i missed that part.. forgive me

 

replaced bad fan relaya week later radator blew up in trafic the macaic replayedthermostat. it been 3 weeks and fans not working again / overheating ??????????????[>:]

 

The fan module maybe shorted and causing the fan relay to be inop. You will need to actuate the fan relay and see if the goes on. If the fan does not spin the relay maybe the problem. If another works and kicking the fan on, I would replace the fan module too.
