UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Greg (Indy-Tech).Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.Rgds Greg.
First i suggest you get hooked up to a scan tool and check for suspension malfunction codes ,
As in most cases the most common issue would most likely be one of the level sensors causing you this issue .
If no scan tool then check a good GM shop or a local GM repair shop .
The maxidas DS 708 and 908 will work on the suspension system ,most indy shops have these tools.
Attached is the wiring diagram in two parts ,print and then tape together .
Need further assistance with this issue then please get back to me with the reply box below .After rating there is no further cost for any other question relating this issue .Kind regards Greg
