Hi Agape, You said in an email
>>>Thank you for your reply about having to remove the AC compressor to repace the clutch on 95 Windstar. You are correct. In doing some additional research however, I discovered that there is usually something else that malfunctions in the system that takes out the clutch.
I'll give you the symptoms and maybe you would be kind enough to give me some additional information.
The cool air stopped flowing when the car was idling or moving at slow speed, but seemed to work OK at highway speeds. However that gradually diminished as well and then a clicking sound started whenever the clutch was engaged which led me to beleive it was the clutch. I did purchase one of those R134 refill units with the gauge which showed "red" indicating a problem with the system rather than low freon.
I do have a Haynes manual for this vehicle but no information about clutch replacement.
Thank you for any help you can give. I really appreciate people taking time to read stuff like this and share their knowledge. God bless!<<<
Well, initially reading about how you had poor cooling while stopped and better on the road I wondered about your electric cooling fan. It should be on whenever the A/C is on. Is it? (just in case..... I am talking about the fan under the hood that pulls air through the A/c condenser and the radiator) I imagine it is or you would probably be overheating too.
The clicking sound....are you sure your A/C compressor clutch is engaging and then the clicking sound? Or, could it be that the clutch is engaging, then quickly disengaging, then engaging....etc..... Take a close look. Low freon is often accompanied by rapid clutch cycling (it can also go along with low condenser flow...the fan ?).
Another shade tree way of checking freon level in general......If the A/C is on and has been running a few minutes...the two aluminum A/C lines coming out of the firewall at the back of the engine compartment should be about the same temperature, and both should be cold. Use your hand to feel them.
I just re-read your post regarding the "red" indication on the guage. I am making an assumption that it is sensing high rather than low pressure (if your a/c is working properly, the pressure on the low/suction side is down around 25 psi. With the system off and static, it is around 60-80). Did you attach the can with the engine running and A/c selected on max? If so, I am thinking the A/C compressor (clutch) was not engaged and running.
I'll be around over the weekend. Why don't you spend a little more time looking at these things and let us know what you find out.
Always happy to try and help. I learn as much as I share.
