Can a bad AC compressor cause rough idle?
When the additional load of your AC compressor is added, it causes the computer to miscalculate and increase idle speed too much. Bad Belt: One often overlooked cause of a car surging with the AC on is actually a worn compressor belt.
Does AC compressor affect car performance?
Because the system is powered by your engine, using AC will pull energy from it, which can affect engine performance. When the compressor kicks on, your car’s engine RPMs may increase. The power used by the air conditioning system is offset by this.
Is it OK to drive with a bad AC compressor?
It is most likely OK to operate your vehicle even thought the a/c compressor has failed. As long as the compressor pulley is rotating smoothly, without wobble or noise, it shouldn’t affect belt tension or operation of the other belt-driven accessories.
What happens when a AC compressor goes bad?
A failed or bad air conditioning compressor will not circulate refrigerant in the air-con system, and the outcome will be warm air coming through the AC vents. So, when the AC compressor fails, you’ll notice high degrees and hot airflow inside the car.
When does the a / C compressor engage at idle?
Here is where the problem started: that night after changing my battery, I went to use the defroster. When the A/C compressor engages at idle in park or neutral every five to ten seconds the idle drops and will either almost stall the engine or occasionally does stall the engine.
When does the a / C compressor engage, the engine stalls?
When the A/C compressor engages at idle in park or neutral every five to ten seconds the idle drops and will either almost stall the engine or occasionally does stall the engine. This happens in drive as well, and when driving, since the rpm’s drop and come back up, the vehicle surges at low speeds.
When does RPM drop when a / C compressor engages?
The rpm drop only occurs when any A/C component is on (A/C, defroster, or re-circulation), when just the vent is on, the rpm does not drop and the engine run fines. Please help me with this question, it seems like this is not a one of a kind problem.
