Question Asked: A/C pump OR ????
August 24, 2010, 09:58 AM
I have a 1996 Sable that for the past year, I have had to drive at 30 miles per hour for the a/c to be cold otherwise it's warm. After driving for an hour to the airport at 75-80 mph, I started my car to go home an it was making a serious noise. I added a quart of oil and very little anti-freeze and as I was driving home the noise stopped. I continued the 1 hour drive home (no noise) and the noise started as soon as I got off the freeway and down to 35 mph. We thought it was the water pump, but it never got hot. So now we think it is the a/c compressor or condensor or ???? Does anyone have any ideas? The a/c unit is EXPENSIVE!!! Before this happened it came up with error codes: P1507, P1504,& P0401 1) idle air control underspeed 2) idle air control circuit Could any of these be the problem? PLEASE HELP!!!!
