2002 GMC Envoy SLT. The rear suspension has completely collapsed. The compressor still attempts to inflate but the rear does not rise. Here's the kicker. It only happens on rainy days. About 10 hours after the rain ends the suspension system behaves like it should??? What gives I've had the vehicle for about 6 years and never had an issue with the suspension or rear recreational air compressor. I'm assuming a short or electronics issue? Please help. I'm somewhat handy around the vehicle and would not mind trying the fix myself. I just don't know what to replace/fix.
