ELC problem
Ok, if you don't know, i was rearended 2 weeks ago while driving home from work. Everything is fixable, except i have an immediate problem. My ELC pump isn't working. Just started to notice a couple days ago it looked lower than usual. Now it'* about 2-3 inches lower than normal. When i turn on the air hose part, the relays on the passenger side of the trunk click like it'* turning on but the pump isn't working at all. Is it possible the accident killed the pump from the jolt?

First, we have to check if 12V is getting to the switch/compressor. On the compressor bracket is a wiring connection that goes forward to the elc switch. The red wire should be hot at all times. the brown wire should be hot when key is in run position. if this is the case, put the key in run, and put the yellow wire to ground. this will turn on the compressor. Do these tests, and report back.

No, it is not. And the bracket is different as well.
You do NOT want to buy this from the dealer or GMPD. It'* going to be at LEAST 300 bucks. You want one from a member or a wrecker.

Or you can convert it to a manual, old style, air shock type system. You lose the ELC but the conversion is very easy. I know I will ruffle some feathers on this site but I never liked the ELC system, except to pump up tires. More than once it left me with a dead battery. Seemed to run way more often then needed. Maybe I had a leak. I disconnected the line in the trunk and connected it to the "T" connector under the trunk. This made the outlet in the trunk an inlet, I control the pressure as needed. Removing the pump made room for my FWI. Just food for thought.

I like the tire pump too much Don. And besides, on my car the pump is behind the rear passenger tire. No problems for placement for me. Thnx for the input tho.
