When I first turn on the car within 5 minutes i hear some Mechanical noise it goes on for about a minute then shuts off. No clue what It could be anyone ever have this issue and could tell me how to get it fixed definitely do not think thats supposed to happen. Thanks!
It starts when i start moving ---------- It does sound like a compressor just never usto hearing that so its new to me just wanted to make sure it was supposed to be doing that and not that something was malfunctioning
Easy way to tell
Turn the key to run(engine and hvac units off) and you should be able to hear the air shock compressor kick on
I know I can hear mine with the window down sometimes with the engine running but not every time
I had the same thought with my new to me 'lade last week. But then I was crawling underneath and noticed the ride hieght sensors and compressor. Found a few threads on this site about the setup...not worried anymore. luckily my shocks/compressor seem to be in good shape and I only hear the noise every blue moon
The original owner was telling me that the sound is the traction control and it does it everytime I turn the car on for the first time. Also now i have noticed it has been doing it more often even when I am driving. Anyone have this problem before? I want to know how to fix it im pretty sure it shouldnt be doing that. Also he said he disconnected the air shocks and put regular shocks in would that have anything to do with it? Thanks again
Traction control doesn't make noises. Ever! TC is a strategy the PCM uses to prevent/stop wheelspin by using brakes, ride height, etc
It does sound like your rear air compressor is pressurizing the rear air lines for those missing shocks. Crawl underneath and see if you have 2 pressure lines that aren't connected to anything. at the very least, those lines should be capped/plugged. If the lines are missing, check the air pump itself to see if the connections are capped/plugged
there is apparently a conversion kit to go from air-ride to traditional shocks for our cars. hopefully the prior owner did that. do you have any messages on the messenge center?
