the switch is on a port with a schrader valve... no evac necessary.

MAKE SURE the new O-Ring with the switch is as thick as the old one.

Better yet just leave the old one there, no worth taking a chance on
scratching the seating area.

That was also my plan but the old one split when I went to put it on the new
switch. Picked up a new one at my Ford parts department ($0.50) and had them
have the shop coat it in refrigerant lubricant for me.(brought my own ziploc
bag)

Ok, I'll tell my brother -in-law to give it a couple of whacks.
Hopefully that will solve the problem. I'll keep you posted.

Did you fix this?

I am not the original person that posted the problem with the A/C but I was
having the same problem with a 94 Mustang. I jumped the connector to the
cyclic switch and confirmed that there was power, then I removed the switch,
tapped it on the garage floor a few times, put it back on and now have nice
cold air.


Thanks for the info, it worked for me!

I am going to see my Brother-in law again today.
I'll let you know if it works.

Well, we tried to tap it, and it did't work. So now we have to
investigate further. Could be in the climate control unit inside.Thanks
for everyones help.
