Drivers side Cooling fan does not run
I am trying to sort out a engine cooling fan issue on the 95 I recently bought.
The initial problem was as soon as the key was turned on, both fans came on slow speed. I quickly found that problem. Someone in the past spliced into wire #335 dk green on fan relay #1 and ran the wire directly to ground. This turned on both fans as soon as the key was turned on. I removed the ground, fans do not come on with key.
Now when the engine reaches 228 degrees, only the right fan comes on and shuts off about 220 degrees. The left fan does not run. Turn on the AC and only the right fan comes on. The left fan never comes on.
The A/C in the car works beautiful, all the cold air you could ask for.
Looking in the FSM Section 6E3-C12-4, I dont see how only the right fan can run since its in series with the left fan at low speed, both fed 12 volts from the 30a fuse on wire #1442 Red. I know the drivers side fan is good since both fans ran when Relay 1 Dark green wire was grounded.
Your thoughts Please

Your 95 (and the 96 is the same as your 95) is set up differently from my 94. But I would look at the relays there, I think your year has three that are identical. Try swapping them around after you verify they are the same and see if you have a bad relay.

The fan issues have been resolved. All is now working like the General designed it.
Bubba and his father worked on this car. For some unknown reason, some Bozo, felt it was necessary to cut many of the wires going to the fan relays. They then
rejoined them with crimp butt connectors. Some of the crimps were not even on the crimp area, but rather they crimped the plastic.
I removed all the crimp connectors and soldered them with heat shrink tubing and finally put them in split loom. It was a good day, nice to have the fans running properly.
