Hi all,
my sister's 1991 940GL is having some issues and I have no clue as to what is causing them. The first issue is- the coolant temp sensor isn't working on the dash. Our mechanic checked it and said that nothing is coming from the computer for a temp reading to the dash. The second issue is that the AC isn't working correctly. Our mechanic checked the freon level and said it was almost completely full- but compressor and fan we not activating. He thinks that is also related to something electrical or in the computer, because he could use a "hot" wire to activate the compressor, but the fan didn't come on. And the last issue is- the ABS light came on when my dad was trying to put the car in gear. He had to turn the car off, restart, and then was able to put the car in gear. So is this all computer related or indication of a bad computer or what? I'm at a loss, cause I've got a 1983 240 and I'm not seeing any similarities to probs I've had. Any help would be much appreciated! Thanks again all!
