air suspension 2000 marquis

Question type: Maintenance & Repair

My marquis's suspension light comes on all the
time as my rear sinks or sits. I hear the pump go on
all the time . Do I have a leak or is it a fuse issue,
any clue. I was suggested by a mechanic to fix the
air ride even though more money. IT'S THE RIDE!

Check for leaks first, might have a pin hole on one of the air hoses, loose or bad air fitting

Thank you! I'll do that with the soapy water, like a tire. If not, grab some flex seal or duct tape


yeah soapy water will do the trick


Compressor could be bad, air bag could be bad or there could be a leak. Those systems are very simple and easy to work on.
