Having problems with your 2005 GMC Envoy ?

My air pump wont come on - 2005 GMC Envoy

Answers :

There is a relay that is on the right shock tower, just above the A/C line. This would be most probable if you have verified the pump is not locked up. Now the ecu supplies ground to this relay to trigger the pump.

Thanks for using FixYa.

Try to check the fuses under the hood or under the dash. See if there is any poped fuse.

I hope this helps. Thanks and good day.
