the 2007 Tahoe doesnt have a AC filter i was wondering that to and called the dealer and they said it doesnt have one.
AC Delco PF46
Did you check the fan?
recharge gauge shows pressure of 70 psi
Depends on the brand you buy. If you buy an AC/Delco which I recommend, get a PF46 oil filter. .
Under the air filter compartment.
You can find the air conditioning drain on your 1999 Chevy Tahoe on the bottom of the air conditioner compressor. The condensation drain hose routes water to the bottom of the engine compartment.
compressor maybe sticking which doesn't filter freon through the system

If a person is going to make changes to a car, a diagram can help them do it properly. An Ac system diagram on a 1996 Chevy Tahoe can be found in its maintenance manual.
If you mean the fan works on high only it's the blower motor resistor.
