What to when alternator on a 2003 trailblazer is replaced and idle drops below 500 RPMs and engine shuts down when AC compressor engages?
Check all wiring connections and grounds. Also verify the voltage of the alternator and that it is not interfering w/ the computer. It could also be a vacuum leak or your idle air control valve is faulty. Try a turn up first and work your way up. There are many variables involved.
What else can I help you with?
AC compressor - clutch seems to be locking upmaking noise can only the clutch be replaced or does the entire Compressor need to be replaced?
If the AC pulley is locking up when the ac compressor clutch engages, it's not a clutch problem, it's a compressor problem. But yes, the AC clutch can usually be replaced separately. The problem is, if the clutch is worn out the compressor is probably worn out as well. It usually isn't that much more to replace the whole thing.
Why does your engine stop when you put your air conditioning on?
Check your battery... The A/C Compressor is probably bad. I had the same problem and when you turn on the ac it engages a clutch that is driven by your fan belt and if the compressor is bad it will stop the belt from turning and stall the engine. The same thing will happen for a bad alternator.
What does a pressure cycling switch do?
Engages and disengages the compressor clutch as needed.
What is an AC compressor clutch and what does it do?
The AC clutch is on the front of the compressor where the belt rides. When power is applied to the clutch it engages to turn the compressor. It is basically a magnet a/c compressor clutch is the ound thing on the front of the compressor with pulley wheel attached. this clutch is an electro magnetic clutch that when electricity is supplied, engages so as the a/c compressor is driven ,which can then pump freon thru the ac system
What could be the problem with a 93 Ford Ranger its filled with freon R134a compressor engages disengages as it should but still blows very hot air and all the major ac components have been replaced?
burn it
What belt do i need to bypass the ac compressor on my 2001 Honda Civic lx?
The A/C clutch only engages when the A/C is on, so unless the pump is seized and you don't want to fix it, there is no reason to put on a "short belt". The belt that runs the A/C also runs the alternator so if the compressor is seized you would need a shorter belt to drive the alternator. The best way to measure would be to adjust the alternator bolt/bracket midway or slightly shorter and measure with a string and find a belt that is close.
Why is your ac compressor smoking when ac is on?
The Air conditioning compressor is likely seized. There is a clutch in the pulley that engages the compressor when the A/C is turned on. You can easily check the compressor (with engine off make sure the pulley has had time to cool off as it will be very hot) Try to turn the most center part of the pulley. If you cannot turn it by hand the compressor is seized. The smoke was MOST likely from the serpentine belt rubbing on the seized pulley when the A/C compressor was engaged. Please note that the same belt drives the power steering pump. This belt will be destroyed from the heat and must be replaced to prevent a possible steering failure.
Why high side gauge fluctuating?
Well, that depends on exactly how it's fluctuating. If it drops when the compressor clutch is disengaged and builds back up when the compressor clutch engages, that's normal operation.
Power steering belt squeals when defrost is on?
Tighten the belt. The belt drive the AC compressor. On some cars the compressor engages when the defrost is on to remove moisture from the air before it's heated for the defrosters.
A C compressor engages often?
It's called short cycling. The most common cause is low freon. Take it to a mechanic for diagnosis.
Why would the air conditioning stop working when car stalled in pooled water?
The A/C compressor is clutch driven, when electricity is applied to a coil, it engages the clutch. Most likely the coil shorted out in the A/C clutch on the front of the compressor.
Do you need a new module When you turn off the blower switch the compressor engages and when you turn it back on the compressor disengages?
Sounds like either a defective relay or relay wired incorrectly switch the wires over.sounds like wires are on backwards
