    Checked all fuses and swapped control relay in underhood fuse box. Shorted low pressure switch - NO JOY. If the diode for the power delay/surge protection opened would it stop the compressor from starting? Compressor less than 1 year old, if clutch is bad How do I verify it?, and should try to replace clutch only?

I have a 99chevy lumina 3.1 6cylinder the a.c. is not getting cold last yr worked great it's just blowing hot air

Can you do a quick observation for me and reply - you can probably do it by yourself - sit in the car with the vehicle running - no radio, etc. and leave the ac off. Once it's idled down and running smoothly, turn your ac on to low - low will keep the fan noise down.

When you turn your ac on - do you hear like a single 'click' and does the motor sound as if it's a little more strained than it was before you turned the ac on? Your compressor (I'll attach a pic) has a 'clutch' on the outside of it - when you turn your ac on, that clutch needs to engage - that's the click sound. Your engine will usually sound like it's under a small amount of strain. Which is normal.

When you turn it off - you should hear that same click, maybe not as predominantly - but the engine should feel as if it's no longer under that strain. This will tell me if your ac compressor's clutch is engaging or not.

We can go from there - all the best, hope it's an easy fix - summer's here without a doubt.

Mary - that part on the front, on front of the assembly - that's your clutch for your ac compressor - this is just a reference - if you stand outside the car and watch - when the car is running but your ac is off, the pulley spins - but that piece with the triangle will not spin with it. When you turn the ac on - that piece on front of the pulley 'engages', makes a click sound - and spins also. That's the clutch - and the assembly in the picture is an ac compressor.



The top pic the clutch is engaged - the bottom pic - this assembly is a little different - but these give you an idea of where to look if you can visually observe. Your belt will go around the ac compressor just like the power steering pump, alternator, etc.


All the best, I'll keep an eye out for a reply - Justin McCartney

AC compressor clicks on and off while running?

the compressor will cycle on/off when the cabin temperature is reached
the larger pipe will be cold to touch as it is the suction line for the compressor
if you have a problem with the ac ,it will not work the compressor at all and the lines will not get cold
When in doubt take it to an accredited ac specialist shop and have the system check out.

My 2010 Ford Escape XLT air conditioning is not blowing cold air. I can hear the compressor kicking on but the blower is not coming on.

Check the pressures. To listen to the compressor, have someone sit in the vehicle, open the hood and listen by the belt area for a click while someone turns the a/c on in the vehicle. The compressor clutch will make a loud click which can be easily heard when it engages to turn the compressor on. You should have your low and high side pressures checked by a professional since the majority of AC system failures are due to leaks. If you have low pressures while the system is running, then most likely you have a leak. If you do need to replace your ac compressor this site looks like it has cheap prices, free shipping and great reviews

The ac in my wife's Buick Century stopped blowing. When I turn it on I hear a clicking sound near the engine.

On this model you may have developed a leak at the AC compressor and the system is low on charge, that would account for the clicking. If the system is low replace the AC compressor in stead of repairing it., it is accessed through the wheel well liner on the passenger side and from under the car. You can buy rebuilt compressors for this car on eBay for cheap, have on on my own Buick and has been on there for years.

No AC, then recharged, now compressor makes on/off clicking noise while running with AC on

This still sounds like low pressure. If you re-charged a system that was low, and didn't pull a vacuum and evacuate the system first, then you still have air in the system, which is causing the compressor to cycle on and off.

Clicking noise when the car is idling and AC is on. Now there is no cold air only hot air when the AC is on

This most likely is a symptom of low coolant presure. There is a pressure sensor both in the compressor and near the drier / expansion tank on the right side of the radiator. If either one of these senses low pressure the AC compressor clutch is disengaged. The clicking your hearing at idle is probably the compressor clutch cycling. You can watch it cycle by watching the front of the AC compressor pulley. Your watching for the center part to turn when AC is on and not turn when AC is off. Usually this is controlled by a temp sensor but if there is low pressure the preure switches will cause the compressor to cycle. Here is the kicker... you can pay to have the system serviced but.... if they pump it into a vacuum and it won't hold a vacuum there is a pin hole some where in the system usualy the evaporator coils inside the front passenger compartment. No one will re-service the coolant system with a system leak. It is against the law in most states.

Ac compressor not switching on 1986 Peugeot 505.GTI How can I test clutch wiring,. Have just aquired this car , heater blowers etc. working but ac clutch not cutting in, is there a switch I have not found....

The best thing to do first is to check the AC clutch itself if it's working, locate the air - con compressor and you will see a wire coming out from the front top of the AC-compressor, it has a connection, remove tht connection and take a piece of wire, connect it to the wire frm the AC-compressor and the other end of the wire to the battery positive terminal,by doing so you will hear a clicking sound of the clutch at the AC-compressor, better still is to start the car's engine, switch 'ON' the AC as normal, let the blower blow thn connect tht wire frm the AC-compressor to the positive side of the battery terminal and check it out if the AC-compressor rotates and also you may get in the car and see if its blowing cold air.
Please also check this -->
HEAT/COLD selector (on the dash) is not selected at HEAT...if it is thn the AC-compresor clutch will not kick in!
Hope this helps!

AC Compressor clicks

The noise is the clutch on the front of the AC Compressor. This is a common problem on late ninety's Doge Rams. The clutch is inside the AC pulley. It is electronically controlled. Their are two wires coming off the AC compressor near the pulley. Follow these two wires and you will find a wiring harness connector that you can pull apart. Disconnecting this connector will stop the clutch from activating, saving you a little bit of gas too. But the AC will not work while these two wires are disconnected. I disconnect these for the winter to save on gas and noise. I don't know what causes these to activate so much.

Could this be my compressor going out?

The AC compressor shaft is riding on a electronic clutch pack.

When the pressure need to built up the clutch will LOCK and you will see the shaft start spinning.

Start the car and max out the ac. The clutch should lock up within 2 minutes.

Listen for a click sound from the clutch.

A badly damage clutch will lock up the belt!

You DO NOT want to be anywhere near the belt because it will snap.

An AC system should last 3--6 years.

NO using the ac compressor is a bad thing.

Let an AC guy to test the low side AC line pressure.

Good luck
