Thank you Weerab and Weasel for your replies - I sincerely appreciate the feedback, as I'm a bit lost in all this - but like the challenge to figure this out and to resolve it.

Here are the exact symptoms (seem to be similar to Nitrogass2000):
1) Front left (only) is very low > fender is about 1 inch above tire
2) Errors message reads: Suspension is inactive
3) The Air Bag on the front left Strut is completely collapsed (see photo in previous reply)
4) Vehicle rides "hard" and bumpy
5) When I turn on the engine, no pump is activated, car does not seem to rise or change elevation.
6) Checked a series of fuses in the glove box, high-amp behind spare tire and right hand compartment in the trunk (based on instructions found in another thread) >> All fuses seemed to check fine
7) Dashboard switch to raise and lower car does not light up and does not seem to work.

Wow, that is a lot of stuff

I guess I'm trying to avoid ordering a bunch of parts that actually dont need to be replaced.

What is your best guess what steps I could take to narrow this down and troubleshoot?

Again - thank you for your insight.
