GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
Ian,Are you able to scan the suspension system to see if there are any fault codes setting?
Hi Ron No I do not have a code reader that would read suspension system codes.
If you can get access to one and get the fault code and or codes it would go a long ways towards finding the problem and getting it resolved.
I will probably have to take it to a dealer to get the code read and the springs are completely down now so my envoy is very low and riding on the jounce rubbers.
Any automotive shop can scan the system for you as well as your dealer.
I know but that`s 10 miles over rough roads . Is there anyway to pressurize the system using the tire inflation valve in the hatch.
Unfortunately there is no way to manually fill the system.
Your very welcome and thank you as well.
