Question about Ford Mustang

1 Answer

I replaced an AC clutch. I tested it with lead wires, it engages. When I plug it in with the AC on it will not engage. I have 13 volts to the plug with AC on. what would keep the clutch from engaging if I have voltage to the plug?

Hi

Here to understand why it’s not engaging first check the electric system, fuses, circuit breaker, and connection to the clutch assembly. Chances are your refrigerant level is low and the low pressure cut out switch is preventing the clutch from engaging in order to protect the compressor. You can jump across the terminals at the overload fuse to check operation of the clutch but only for a short period of time in case your system is low on oil. Evacuate and recharge the system to resolve the issue.

Let us know if you want to know something else accept the suggestion.

    I jumped both the high and low switches. I have power to the plug. For some reason it will not energize the coil. I know the coils CAN be energized because I jumped it straight to the battery.

2003 Ford Windstar AC is not working. It only blows out hot air. The blend door act. works properly(We have already tested it). There are properly freon in the Vehicle. We are at a lost. Please help


Can you tell if compressor clutch is engaged? If clutch isn't engaged only the belt pulley will be moving and the compressor clutch is not engaged. If not engaged, no ac.

Can you check for applicable hvac codes? To check codes, your-self, at the least, you need an obd2 code reader, that will check manufacturer specific codes as well as po.

I haven't looked at your wiring, you could probably check voltage and ground for compressor, hvac on.6158ef87-8677-4b29-952a-e287698970b5.jpg
In the diagram, you see applicable fuses--clutch relay-- the top wire at ac clutch is voltage--black wire is ground.

Ac not working, air compressor clutch not engaging


Hi Adeyeri

Keep in mind that the Clutch won't engage for a few safety reasons.

Temperature inside vehicle
Temperature of compressor or pipes
Pressure inside pipes
Compressor jambed
Eg It's out of refrigerant Gas

You can momentarily engage the clutch by simply giving it +12v to the wire attached to clutch. Usually has a connector close by.
Or
If it has a Relay (click) in fuse box
You can by pass it with a jumper

A quick engage & disengage should allow you to detect possible problem.
But don't over ride the built in safety for more than about a minute.

Cheers
Hope this Helps

When you changed the compressor, did you recharge the AC system? If the pressure switches are not actuated by the correct pressure, the system will not engage the clutch. To charge the system you have to pump a vacuum on the system for about an hour. Follow the new compressor instructions as to the amount of oil that may be in it and how much the system calls for. See it has the correct type oil and the correct amount, then charge with the correct refridgerant and the correct amount.

1993 accord ex ac not blowing cold replaced compressor last year freon level ok unit not engaging is there an easy fix?


With the engine turned off, test the a/c compressor clutch by applying 12 volts to the contacts. You should hear a click of the clutch engaging, and if not, the clutch is acting erratically.

A/c has full freon but the compressor clutch wont engage. i have found that the plug going into the compressor is not getting any power. what could be the problem?


On the low pressure line of the ac you have a pressure switch which allows the compressor to come on once a certain pressure is reached, and it will cut the compressor off if the pressure is too high or too low. Look at your ac hose and find the switch *you will see wires connected to it* you may need to replace this switch. You can use a test light to see if you are getting power to the switch. You should check you fuses, and the ac relay witch is usually in a black plastic box under the hood.

Compressor clutch wont engage. sometimes on sometimes off. now just off


Trace the clutch wires from the compressor clutch to the nearest plug that you can disconnect. With the engine running, and the AC set to max, check to see if the clutch is engaged. If not, unplug the clutch wires and check the voltage going to the clutch. If the voltage is around 12 volts or more, then your clutch is shot and you will have to replace the clutch and compressor (sold as one unit). If the voltage is low or zero, then your AC is not calling for the compressor to run...a pressure or temperature sensor in your AC is out. Hope this helps.

AC blowinghot air


Locate wires coming from compressor clutch and trace to nearest plug that you can unplug. Turn on A/C to max cooling. If clutch not engaged (center of compressor drive pulley not spinning with pulley), unplug compressor clutch wires and use multimeter to check voltage going to compressor clutch. If voltage is around 12 volts or more, then clutch should be engaged when plugged in. Plug clutch wires back in (with motor still running and ac set to max). If clutch still not engaged, then clutch definitely bad because 12V signal should engage it.

The ac clutch will not ingage the two wires that go to ac clutch never have 12 volts on eather one


You need to have it leak tested and recharged. There's a low pressure switch that won't alow the compressor clutch to engage when there's a leak. If the compressor clutch was engaged without refrigerant and oil circulating it would seize. Don't be surprised if you need a new condenser. Don't use those leak sealer recharge kits as they can do more harm than good, and some AC shops won't touch a car after someone uses leak sealer. They claim there's a different mix of gases in the refrigerant (usually propane) and they can't recycle it, and they don't like customers complaining when the AC doesn't work when it was the leak sealer clogging things up.
