SOURCE: When the air conditioner is on, there is a loud revving sound that gets louder as we accelerate. It goes away totally if the ac is turned off. Could this be the tensioner?

Yes it could be the belt tentioner or you may want to check the front clutch asy on the a/c compressor.sometimes the clutch will squeal when it is trying to lock up.

SOURCE: Air conditioner problem 2001 Dodge Pickup

Hello, It sounds like your hot/cold blend door actuator is either hanging up at times or it's loosing it's calibration range because it's starting to go bad. The ticking noise is most likely the actuator trying to close off the hot air port but is unable to stay closed allowing hot air to mix with the cold. If it's just a weak blend door actuator, it will act up more when the air is on full because it has more resistance due to air flow. If possible try to see if the times it acts up decreases when you start the A/C with low fan speed.

SOURCE: air conditioner quit working

If after switch on of the a/c there is no difference in the engine rpm with the solenoid latching up the a/c compressor with the fan working , then you must look for the fuse of the a/c which can be found near the main box inside the bonnet. replace and test. However if the ac works but there is no cooling then you must check for the gas pressure in the visual eye at the gas inlet. If you notice that there is heating in the cooling pipes then your compressor needs to be checked, gas leak in system, gas filling. Hope you check this out. Good day

Car makes very loud screeching noise.


It could be that the air conditioning compressor clutch is not working properly. The clutch should allow the pully to freewheel when the air conditioner is not used.
You can have your battery tested at.an auto parts store, and you can test the alternator by removing a battery cable while the engine is running. The alternator is what powers all the electrical systems while the engine is running. If the engine stops running when the cable is removed, this means that the engine was running from the battery and not the alternator.
Your alternator or your regulator is bad.
Regulators are an internal part of alternators, unless its a pre 70's.car where they were a separate external unit.
Hope this is helpful.

Car makes loud noise starting


sounds like your starter needs shimmed and/or replaced or you have a flat spot on your flywheel. the sound your hearing is from the starter motor gears not properly aligning with the flywheel gears and quite literally grinding material off of one or the other. if you continue to force it your flywheel will need replaced if not already

My blower fan for the vent, AC and heater and defrost, on my 1999 Buick Regal made strange loud screaming, screeching sounds before it quit altogether. Which fuse would I replace to make it work again?


If the motor was making those kind of noises it is most likely the motor itself needs to be replaced. It turns on bushings instead of bearings and they wear out making that kind of noise when they do.Hope this helps.

Screeching noise when I turn on my air conditioner or heater


It may just need to be adjusted (it sounds like it's too loose). If the belt isn't cracked or frayed, you should just have it tightened up a bit . If there are signs it is worn (cracked frayed) replace it.
