I have a Sorrento EX (2003). Air blows cold for first half hour to 45
minutes. Then, air begins to blow warmer and eventually no cool air at
all. If I shut off A/C for 15 - 20 minutes and then turn back on, it
begins to blow cold air again.

Does anyone have a similar problem or suggestions? My guess is it may
be low on refrigerant or possibly a bad low-pressure sensing switch.

Thanks.

Sounds to me like the temp switch is cycling the unit off due to ice
forming on the coils. Check the water drain line for an obstruction.

Also, if you see a decrease in air flow at the same time the unit stops
delivering cold air then you should assume the coils are icing up.

Chris,

This is exactly what is happening... the fan does not blow as hard
after a while. I'll check for the blockage. I assume since it does blow
cold initially that the level of refrigerant is okay.

Thanks again Chris.

Get it recharged sounds like your low on FREON or you can get a KIT but
get one with the gage on it and do it yourself.
