SOURCE: 97 safari fan does not blow

Check to see if is blowing out defrost vents if it is you have a vacuum leek. The tube is hard to get to take of dog house you will see a group of tubes on connected to a clear plastic junction. Once you get the dog house off one of the tubes goes to your manifold vacuum fallow them its very thin and the engine heat makes it brittle and they fall apart . Mine did same 2 shops 500 dollars and they never found or fixed it used window washer tubing to fix 2 years ago still works great,

Temp gauge often reads too hot, engine normal.

It sounds like your cooling fans are not comming on by themselves, but when you turn on the ac it forces them to turn on. Make sure relay is good, then replace coolant temp sensor, this may have failed no telling pcm to turn on cooling fans. Thanks

check the switch for the fan it could be the reason why only the high works. You may check on the wiring from the switch and on the fan. It could also be a defective fan
