Air conditioning When you turn the air on the clutch only engages for 2 seconds and retrys every 5 second or so. Tried filling up the 134a but no difference. Any advice would be really appreciated Thanks

Did you check system pressure? approx. 30lbs.if ok then either comp. clutch coil is weak, too much clutch gap, pressure switch weak, relay is cutting out too early. also check high side pressure to confirm plugged in line filter.

Air conditioning system freon


You'll need to have a mechanic check the system to see if it is low on freon, or if you have an electrical problem.

What would make the AC clutch turn on an off repeatedly, approximately every 4 seconds on an 99 chevy Suburban 5.7L 4x4 LT? Only blows out hot air


low freon soumds to me.. jump out the low pressure cut out switch near the dryer...or jump clutch relay in the distribution center. with clutch ingauged hook up guages to check low and high side pressures... also easy trick go to auto store get a can of 134a freon with hose and add the can the clutch should stay inguaged longer and longer as you fill the sytem... with clutch inguaged rev motor up to 1500 the guage on the hose should be around 35 to 40 pounds if low add more

AC BLOWING HOT AIR. JUST ATTEMPTED TO ADD R-134a REFRIGERANT BUT THE GAGE SAYS IT'S FILLED. WHAT ELSE COULD BE THE PROBLEM AND HOW CAN I SOLVE IT?


The clutch to engage the A/C compressor needs to be energized. Open the hood and have someone hit the A/C on switch, and listen for the clutch to engage. If not, check wires and fuse. Also, pressure switch for control and A/C relay.

AC not blowing cold air/ clutch not engaging


you might wanna check your a/c relay and make sure its good if that's fine you might just have to get another compressor also by a refrigerant with dye so you can make sure there's not a leak in your a/c lines

1995 Chrysler Condorde air conditioning problem


it can be a relay prob or it might be that the a/c coolant, the R-134a (this is what they replaced freon with), may be low and that you may have to just top it off because the pressure switch within your a/c system may not be engaging because of that.
