Want this question answered?
I have replaced the entire brake system in a 1988 gmc jimmy and still have no brakes can you help/
The recharge valve for the air conditioner on a 2002 GMC Envoy can be found by looking at the rear of the engine compartment. It will have a cap over the valve labelled as low pressure side.
The AC recharge port on a 2004 GMC envoy is on the low pressure connection. It is the larger of two hoses near the firewall.
yes
It is screewed into the passenger side of the engine just in front of the starter.
My husband bought something that sounds similar at our local parts store - comes in a pressurized can - and he recharged the system in our 94 GMC Jimmy - hope this helps !
