A/C help please

hey guys need your help.. working on brothers 1995 windstar 3.8. and the ac clutch didnt work, so put the ac recycle switch on it and the ac works fine now. BUT when you turn the heater on the ac clutch cycles on and off the same as if the ac is on. What do I need to check out now.
you A+ know it all's can answer too. thanks for any help.

I think you've got the heater wire and A/C wire crossed or connected somewhere. Double check and make sure you didn't hook the one a/c wire up to the on position for the heat along with the heat wire.

I have a 98 windstar it does the same time thing I had a/c man tell me no to worry about it is they way they are set up to cycle the a/c refrig. in the winter to keep the system up.My heater has never failed me yet and work fine with it cycleing in and out.

Keith make sure it is full on refrig. if he hasn't used it in a while add a can of oil. If it has the rear a/c run the a/c on high max on both front and back for some reason mine will show the system is full with front on and the back off.I know you have to have the a/c on high max when filling one. But didn't think about it the first time I had to add some to mine and didn't have the rear on that how I found out about it not being completly full without both on but showing full with rear off.An when it is full the a/c will not cycle in and out as much even with the heat on.

no wire's were crossed. just unplugged the plug and put it back on..

Jim, I wasn't sure but was holpeing thats was the case. and yes it hasnt been used for a while.

Thanks for the helpe guys

Nothing wrong with it, that's the way it works. My 88 GT, 93 Ranger, 01 LIghtning, and my wife's 05 Mariner all function the same way.

you guys will like this one....just let my A+ know it all brother read Jim's reply and this is what he said.

that can't be right cause Ive never herd it click on and off before when I turn the heat on.

I can't tell ya here what I said to him.

maybe Jon F needs a helper.

just kidding their Mr.A+

Dan-0 will you make me sign to put on his head.

Tell him mine has 216,000 something miles on it and has done it as long as I have owned it.He probley never notice it until yall was working on it and if the A/C wasn't working is the reason he didn't hear it going in and out.Or let him carry it to the A/C Shop and pay them to tell him that is the way it is set up from the factory.Some times th know it alls has to pay to hear it before they beleave for them selves.
Jim

yes Jim he didn't hear it because it hasn't worked from the time he bought the van 1 1/2yrs a go. he was to cheep to buy a $35.00 part until now thanks again for the help guys.

I thought that the a/c is used when the heater is in defroster mode??? I 'thought' the a/c helps pull the humidity out of the air to help defrost the windows more efficiently...

Have a good day!
