2003 GMC Envoy V6 Four Wheel Drive Automatic 75000 miles
My 03 Envoy air compressor will not inflate the air suspension. The accessory outlet for the compressor is producing about 31psi. The rear end is sitting way down with a little bit of air in the shocks but will bottom out easily. I don't think it is a leak as this is the second time this has happened. The compressor comes on for about 30 sec to 1 min at startup but no increase in ride hight. The last time it happened I parked with one wheel on the curb, re-started the engine and when the compressor kicked in I raised and lowered the back end by lifting on the trailer hitch. This inflated the airbags for about 2 months. The most recent drop in the suspension coincided with a dead (bad) battery. The battery has been replaced. Is there an overload reset? As the symptoms mimic what the manual says the suspension will do in the event of an overload.
