Some 8 or 9 months ago, I had to change the motor because the crank bearings went out and the motor locked up. (It only had 70,000 miles on it.) So, $600 for a used motor(120,000 miles). Anyways, the connection to the a/c connector was different on the wiring harness, so I just spliced the old connector on. At first I just had it taped, but after the relay started blowing I did some research and came across some info about the compressor not being grounded good could cause relay failure. So I soldered the wires together. Then it took like a month before the relay blew again. Then like a week. I got the least expensive relay with only a 1 yr. warranty. Could the more expensive relay(i.e. lifetime warranty) fix the problem? Also I noticed after we got the car a few years ago that sometimes the headlights dim, then gradually get brighter again. Then dim, then brighter, etc. Does that sound like odd or normal behavior? And is the A/C compressor supposed to come on when I'm running the heater?
Anyways, it's getting cold outside and the wife uses the car in the morning to take the kids to school. Any ideas would be greatly appreciated. Thank you.
Hello and good day:
Does the Head light lamps do this "sometimes the headlights dim, then gradually get brighter again. Then dim, then brighter, etc." when the car is idling...or....when you are driving??? And YES the A/C compressor clutch will engage when the heater is on and the the Temp Level is over in the Hot position.....IF WE HAVE BLOWING COLD AIR ...when the Heat..and...temp level is on....then we have a different issue...
As for your other issue...I would likely say you have a Short somewhere...this could be any where...and I am unable to help you in giving you a clue where to look...there are guys here that are well verse in thins and ....."SHOZ" Is one of them...
Good luck on this, and keep us advise.
