Fan turns on after the van has been on for only two minutes.

Asked by maverick0923 Nov 23, 2010 at 02:55 PM about the 1993 Plymouth Voyager LE

Question type: Maintenance & Repair

The fan turns on after the van has been running for only two minutes. The fan does not turn off
during driving, and its running at full speed the whole time. It does shut off once i turn off the
car.

The temp gauge is in the middle and doesn't show signs of overheating. It does take a long
time for temp gauge to rise to normal when i turn on the car. I think it took about 15-20
minutes. Could the Temperature Sender be too corroded. I was thinking of changing the
Temp Sensor and Sender just because the car is old. 1993 Plymouth Voyager LE 3.3

I'm just not certain why the fan turns on immediately.

Any help is greatly appreciated, i even ordered the repair manual for this van but its going to
probably be here until next week.

I also noticed these two connectors that are unplugged, and I'm not sure what they are for, is
it missing a relay? Its the very last connector on the fender if it helps:

this in the picture, not sure what its for:

You've probably already solved this, but for a reference to others who might see it: The two pin connector in your pictures (closest to the firewall, with a small and large tube going into an aluminum block) is the A/C Low Pressure cutout switch. It will keep the AC clutch from engaging if there is not enough pressure (R-134) in the AC system. The round rubber plug half hidden in the front of the picture should plug onto the two pin connector, simply line the wires up to the flat spades and it'll plug right in. The 6 position, 5 pin connector is the chrysler SCI interface. It's a chrysler specific diagnostic/programming interface along the lines (but different, and IMHO, better than) OBD-II. It should be empty.
