What is the ambient or outside temp? A drop of 30-40 degrees is considered normal. And did you evacuate the system to remove the air? This is a must to get 100% efficiency. Another cause is too much oil/stop leak/or leak detector can affect efficiency

The cab of my 2000 chevy suburban 2500 fogs up. I did recharge the ac and the ac compressor doesn't want to kick in. I've been told it could be a heater core but thats very rare. Is there a switch or...

You have a leak in the heater core. It will have to be replaced. It's not all that rare these days, with the poor quality factory heater cores. The replacement cores are much better.

How to install a air conpressor for 1995 jeep grand cherokee

Installing a compressor is a complex job there is alot more to just braking the lines and removing the bolts to the compressor and if you are not sure you really should leave it to a service department.I will tell you to proper steps. First you need to have the system evacuated of freon before you can break the lines.Then if you are installing a new compressor you will need to also purchase the accumilator as well as orfice tube or expansion valve wich ever the case may be. Alot of places will not warranty the compressor unless you change out the accumilator as well as the orfice tube or expasion valve. While you are changing these parts out also change out the orings associated with each part. You will also want to buy A/C flush and flush out the entire A/C system once you have done this begain to assemble the parts but dont forget to oil the compressor and accumilator and put some in the condensor. once the parts have been assembled then you need to have the system vacumed out of all moisture. This is crucial or you will have premature compressor failer. Once the system is vacumed its time to recharge make sure you hook up to the right line when charging the system as hooking to the wrong line will cause your can to burst assuming you are using small cans to recharge.charge only the required amount of freon do not over charge. If your comprssor locked up make sure its the compressor and not the compressor clutch lot less expensive to replace it. Also if its not blowing cold air and only cool air it could be orfice tube plugged up.

2001 Chevy Suburban rear a/c warm front ice cold

I believe there is a expansion valve located on the back part of the air conditioner on the back right side i believe that could be the problem. I think if I am understanding you correctly, your back air is not as cool as it should be or not cold at all. Might want to check this. If I am not understanding you correctly please let me know again what your problem is.

Not cooling

your low for 134A should not exeeed 45 Psi and highs for 134A shouldent get above 300. When your replacing stuff are you cleaning out the residue from your evap and condensor prior to reinstalling Freon?allso adding oil. and vacumeing your system prior to charging helps to get all the moisture out. In high humidity its crutial for optimal cooling and when system is open to the humidity for some time it gets loaded with water and vacuming can sometimes take as long as 10 hours

I have a 99 chevy suburban that won't cool past 60 degrees and when idling is at 70 degrees. I have replaced the a/c compressor, orfice tube,the accumilator,rear expension valve, and fan clutch. My low...

These numbers are a little high depsite the high ambient conditions.Amazingly enough ,automotive low side suction pressure will equal the degrees its putting out at the evaporator coil...for instance,70 psi low side pressure will produce about 70 degrees of cooling. At 300 psi on the high side(which is high) this is about as low as the suction pressure will need it to go lower.I would probably be concerned with the freon level as a slight overcharge could boost these numbers.Poor air flow through the condenser can also create a higher head pressure than desired.If possible,I would evacuate and re-charge the system with the correct amount of 134a refrigerant. Try to get those pressures lower...about 250/50 would be a decent pressure value in this ambient condition.Verify good airflow through the coils and pay close attention to any foreign debris like plastic grocery bags or wrappers covering the coils...Ive even seen these make their way between the small gap between the condenser and radiator so use a light and inspect carefully for this.Air flow through that condenser coil is vital and any deficit there will create high head pressure which obviously causes high suction pressures....good luck

1995 Chevy Suburban blows cold once charged then hours later hot

Its a leak ...probably concealed like in an evap housing or rear air unit and lines (if it has that). Prob at this juncture I would remove all the freon and bring system into a vaccuum with a pump and see if it will hold vaccum for an extended period of time. A bad leak will not hold srong vacuum very long and much cheaper than wasting expensive and enviromental un0friendly refrigerants.
