1993 Dodger Grand Caravan Radiator Fan failure

Model Year:1993
Model: Grand Caravan 2WD
Engine: 3.3L v6
Trans: 4sp Auto
power mirrors only
front/rear Air w/ HD radiator
Miles: 245000

Problem: Today on the way home from work, I noticed the unmistakeable smell of burning wiring coming thru the AC vents. Upon opening the hood, I saw white smoke coming from the radiator fan motor, and the fan was spinning slowly (AC was on). Having no choice but to drive the car home, I got on the road. By the time I got home, the car seemed to be doing OK (no overheat - temp read normal and did not rise unless I had to stop at a light - then once moving cooled off again. Gauge never went much above center). But the AC was no longer working and the radiator fan was no longer turning. The fan motor connector took some leverage with a screwdriver to disconnect, and when I got it out the contact end was rather melted. I restarted the car a couple of hours later, and the A/C compressor does not turn on.

It appears that I need to replace at least one relay and the fan connector, and that the A/C & radiator fan operation is somewhat dependant upon each other.

Finally the Question: the handbook does not show relay locations. It appears that there are 5 on the left fender near the battery, and 2 just fwd of the firewall on the rt fender. Which (or how many) of these relays do you think needs replacing, and is there a fuseable link somewhere in the circuit?

Any help/suggestions would be appreciated.

Do you
have the same problem?

It sounds like the fan motor is toast, and the harness plug end. Replace those and if the fan(s) fail to engage or if it overheats, (mainly with the A/C on), I would change the relay - (not sure of year but the last one I did with this problem was located in the drivers side inner fender up under the headlight area) - may check location to verify on yours.

Good luck
