I have a 1995 f250 and the ac works but it doesn't get supper cold like everyone's esles ac , I put a temp gauge to it and it's only reading 60-65 degrees while I'm going down the road iv put the same gauge on the same truck and it was reading 40 degrees , is there something wrong with my a/c????

 

does the clutch cycle, and what are the high and low pressure readings?

 

Probably just low on refrigerant if your clutch is cycling a lot, but you'll have to put gauges to it to find out for sure.

EDIT: and if it's low on refrigerant then it's got a leak somewhere, so it would be pretty pointless to charge it. Find and fix the leak first. If that's even the problem.

 

It may be just a little low. You should check it with gauges and see what the pressures are. See if your compressor clutch is engaging when you turn the AC on. if it is not it is probably too low on refrigerant to run at all. If the compressor is running feel the lines going in and out of the compressor, the suction line should be cold and the discharge should be hot if it has a descent charge and the compressor is working. You will also need to determine what refrigerant you have in the ac system. If it's just a bit low and it is 134a it's a cheap and easy fix.

 

Well the it seems that the the ac clutch engages in and out very frequently and when I hooked up one of the reusable ac charging gauges , before I eveen when to spray it in the low side it was reading in the high red ??

 

Get some real AC gauges. Those DIYs with the cheap as$ gauges are worthless and can do more harm than good.

Compressor cycling very frequently is a sign of low charge.

Harbor freight had a set of gauges around $50, may not be Snap-On or Matco or any other $$$ brand, but far better than the DIY cans w/hose.

 

It was reading in the red because the gauge on a can is meant to be a low side gauge but without the compressor running, the pressure equalizes in the system and gives you a falsely high reading on the low side. You have to have the compressor running before you take a low side reading.

Get a real gauge set... it's the most basic tool you need if you're gonna work on a/c systems and without it you're working blind.
