OK,

So I registered the car last july, Ac hasnt worked the entire time Ive had it, Now its time to repair the AC this summer is a lot muggier than last year was.

My Question is, The AC Blows hot air, So Im guessing that the compresser is still good, but It is now making a clicking sound,,,, it even makes the clicking sound when I turn the heat on, The heat worked everyday this winter without a problem

Any suggestions on where to look??? or should I just send it to the mechanic and have him worry about it?

The AC blowing hot air indicates that the AC is not working, but the fan is working. The AC not working could be due to refrigerant being AWOL, or a bad compressor, or a non-working compressor clutch, or a bad relay. A bad relay could be making the clicking sound. Actually, the AC is called upon even under heating conditions to dry out the air used to defrost the windshield.

So my vote is for a bad relay, but there could be more parts gone wrong/missing. There are probably some electrical checks you could do, but I usually just let my friendly neighborhood, and good friend, mechanic do the leg work. They have to do so anyway, just for due diligence.

Do you have any idea where I would look for the Relay?
I should just send it to the mechanic.

After thinking about it, the clicking noise means the relay is actually working. The compressor clutch may not be working, or the system could just be low on refrigerant.

My son's Ranger had an AC problem some time ago, where it would cycle on and off fairly quickly and was not cooling. It turned out that the dryer was cracked/rusted through and all the refrigerant leaked out. The system would try to run the compressor, it would detect low refrigerant and turn off the compressor. Over and over. Have someone check the refrigerant pressure and track down any leaks.

I agree with iglen490, in regards to the system cycling on and off due to low pressure.
At some point the system will shut off when the low pressure switch reaches its bottom limit.

Due to your Tempo being a /92, you may have to convert the system over to the new 134A refrigerant, if your system was originally filled with R12 at the time the car was built.

Sorry , but I don't remember when the change over period was back in the /92 model yr. for all T/T's.

I'm one that had to convert my AC system over in my /92 Topaz when it caused me grief a number of yrs. ago.

My /93 Topaz AC system had the 134A in it.

These systems tend to lose refrigerant from the slip-together joints in the refrigerant lines; I understand that the newest joints have 3 "O" rings rather than just the one which these older T/T's use.

If you do have the system changed from R-12 to R-134a, you will need to have the compressor oil changed too. R-12 does still exist and is still legal to use, but you'd need to find a qualified shop and it might cost more for the refrigerant, but then the work would be a little less. In either case, you likely need to change all the "O" rings, both because the older ones get hard or may have shrunk so don't seal, and with the R-134a also because the original polymer is more pervious to it.
The accumulator (which contains the desiccant) likely also will need changing.

if the clutch is kicking in and out, sounds like you're low on freon, mine was doing that, a can of freon and it's freezing me out Smile

Ok, but that clicking sound also starts when I turn on the heat now..... Altho it didnt all winter long.

My car is R12 so yes I already knew it needed to be changed over.

Does the clicking sound seem to be coming from behind the glovebox? My car did this for quite awhile, then it started overheating.

There's a big black relay back there, behind the glovebox, with about a dozen wires going to it. (On my '86.) That's the A/C and Heater Control Module, which is a REALLY expensive relay! Mine chattered until it burned up. $122 new from Ford.

I burnished what was left of the contacts on mine.

But the root cause of the problem is a bad connection at the coolant temperature SWITCH, located near the t-stat housing on mine. Mine has a gray plastic body. The switch itself was ok, but the connector was bad. I put "switch" in capital letters because there's also a coolant temperature sensor.
