Power Steering Randomly Stops Working
Found broken wire to assist, solenoid repaired, no codes, I can not duplicate the problem, all power steering is gone. Customer says it happens randomly.
Electronic Power steering have a control module, are there any codes?
No codes, but let run for hour it was hard to turn, reved motor works fine again.
What is charging voltage?
I had a similar issue with an 07 Malibu.I replaced the module and motor as a complete unit with a used one.Seems as though when they get old they need that extra boost that revving the engine put out.Good luck
This car does not have an electric rack. It has a solenoid on the rack housing that varies hydraulic flow volume thru the rack under various steering load conditions. I would flush the entire system and fill it with Dexron 6 or equivalent trans fluid. See if it still happens. If not I would replace rack an pump with new OE an check lines for collapsing.
Usually it’s the pump ! But may need rack too ! I can’t see the “condition “ of car ! depending on mileage might need lines as well, this era car is usually in much need of some love when i see them !
Check the remote power steering reservoir there's a screen in the bottom that gets plugged. I had a 2010 equinox that had new rack and pump I replaced reservoir and flushed out ps fluid replacing it with DeX 6 and its been a few months without issue.
