If your ac is cool not cold and you are trying to ad freon by the can or you have added freon by the can, you may have an overcharge condition . While its normal to have a small amount of 134 leak during the cold months you should never have to add a can of 134 because your average can is 12 ounces which is 4 oz shy of a pound (that's about a third of your system capacity) you should have your ac recovered and the system vacumed down to remove moisture and air which cause acid to form which ruins a lot of components in a hurry. After you vacum the system to 29inches of vacum isolate the vehicle from the vacum source and watch your gauges if they creep up losing vacum you have a leak, if they don't then add die and about 2oz of oil (pag) and recharge to spec and you shoud have ice cold air. If not then watch your high and low pressures and compare them to the manufacturers specification and follow any trouble tree they have for the symptom

When you change from heat to air , it still blowes hot air like it is not switching to air conditing, the compressure is running and lines get cold, but no cold air. thanks


If the orifice filter is clogged, this will happen, a better check can

be done with an ac manifold gauge set, the low side reads the

evaporator pressure and the high side reads the discharge

pressure. I had the same problem while checking the ac on a

2000 gmc 1500 z71 4x4. other things that could cause this are

to much oil in the ac compressor or not enough freon in the

system. an overcharged system , the best way to check it is with

a gauge that way you can tell if you have the right amount of freon

and oil in the system. plus the gauge set will let you know the

extent of your problem. good luck!

2005 terraza never gete cold enough. in hot


It is hard to diagnose the problem with out knowing readings on the ac system,a low and high pressure readings would need to be known.This is needed to know if it is a internal ac system problem,or a vent door,or temp door problem.Have a mechanic put a set of gauges on the ac system to determine what is going on with the system.

My 1998 GMC Safari ac works well (cold) in the rear. The front AC is just barely cool. Ac reads a good charge, not over or under charged. What could cause this?


The blend door is not fully closed for the front. GM's are bad for that. Also check the vaccuum line for the door.

A/C not cycling and blowing hot and cold air.


Hello msbrig,
This is a REAL SWAG
(stab in the dark... (a bit reasoned))...

Confession... I'm no GM expert... but
General Motors & FRIDGIDAIRE
are the "GREATS" in automotive A/C.

and

This is the BEST DOCUMENTED QUESTION I have
ever seen (congratulations)...

I hope I am not doing a disservice by attempting an answer...

If your vents blow al any time... you ought disregard their behavior.. Likewise temperature controls...
and DUAL EVAPORATRS... front & rear...

The fact that your troubles are intermittent in the FRONT & REAR is a really great SYMPTOM...

You are MOST LIKELY looking at only two POSSIBLE PROBLEMS....

1. - Either your CHARGE is insufficient to keep
the compressor running.(pressure switch monitored)

OR

2. - You have a SATUATED DRYER which is allowing moisture to block your EXPANSION VALVES (internal ice) ...

External frosting is expected...
a lot of external FROST is an indication of #1. (above: low charge)...

A descent refrigeration person should be
able to tell you the HIGH and LOW pressure loads... and watch your system cycle for a few minutes... Which should be long enough to DETERMINE if you are experiencing
INTERNAL MOISTURE ISSUES...

Some folks ROUTINELY replace the ""DRYERS' (desiccant)


I do not... I use brains, gauges, experience... and your vehicles HISTORY

I am here most every day... Push comes to shove... I have the
Lincoln Navigator... dual EVAPORATOR system...
(I'll pull the book & take a look).

You can comment me back...

I bought ALL THE TOOLS years ago... NOTWITHSTANDING my amateur standing... I only let the JAGUAR DEALER jam me for an $800 Schrader Valve since 1965 (Mustang(all the rest... I did myself)).

Happy to chat... comment me back.
(again: here daily)


- Hope this inspires...

What are the readings on your A/C service gauges, hi and low sides? If you don't have service gauges, inexpensive ones can be purchased at stores like: Harbor Freight, Walmart, Pep Boys, etc. The gauge readings are the first step to a correct diagnosis.

Your system may be low on refrigerant. If you also have a rear heating unit, the air mixing door or water valve may not be shutting off. Your expansion valve may be bad in the rear unit.

If you can access your rear a/c, check to see if the inlet hose is hot or cold. If it is cold, you are low on refrigerant. If it is hot and the tube coming out of the expansion valve/orifice is cold, this is the way it is supposed to be. If the tube on the outlet of the evaporator is not cold, then you are low on refrigerant or the expansion valve/orifice may be bad.
