I know I've already posted about my rear schocks on the wagon but a new problem came up and you guys were so helpfull last time.

My question is what happens when the air starts leaking out of the rear shocks. The ride height switch will tell the compressor that the suspension is too low all the time. Is there a fuse or breaker that will stop the compressor before it burns up or will it keep working until it seizes.

I went to the dealer and he told me that the fuse should be 20 amps but none of the 20 amp fuses are blown on my main fuse block.

See my post in the electrical section to find out why I can't find the fuse for the compressor!!

The switch on my car is actually hooked up to the upper control arm and the compressor is right in front of the differential.

I asked the dealer how much and he said $700 canadian for the compressor and $650 for the switch so I hope they are not fried.

Is there any difference between the the stock suspension springs and the automatic leveling suspension springs because my car sits really low in the back now. my hitch scraps the ground sometimes when I back out of my driveway.

the hitch makes a nice skidplate so my bumper doesn't take the hit!!

sorry this is long but I really don't want to change the compressor at that price and I hate paying the dealer to look at it and tell me the same thing I could have figured out.

Thanks for any info

On my caddy, it is position number 9 in the main fuse box under the hood. It was a big green fuse, I think it was a 30amp. Maybe yours will be in the same place?

Your height sensor is in the same place as mine is on the caddy. Just in front of the pumpkin attached to the uca.

I think with the air suspension, they use really soft springs and use the air shocks to keep the ride height at the right spot. With stiff springs and air shocks the ride would most likely be uncomfortably stiff for most people...

HTH!

Thanks a lot I will check that tonight

I hope it is just the fuse cuz the parts are so darn expensive I think I would just put regular shocks on it if it does end up being a blown compressor or switch

i kind of like the look of the car with no air in it but the front sits kind of high

Have to save up for dropped spindles and a new daily driver so I can retire my wagon and really start modding.

I'd just put airbags in. Then you have more choice as to what shocks you put on.

I checked and my number nine fuse is a ten amp but I checked all the 30 amp fuses and I had one 25 amp fuse checked and none of them are blown.

I doubt that GM would do something as stupid as not put a safety on the compressor in case the air shocks started leaking

Although it wouldn't surprise me.

Anyone have any idea if there is a fuse somewhere else or maybe a reset switch on the compressor itself.

thanks

I'll look tonight to see which fuse it is.
Is your compressor running all the time?
If you have a leak in the line (probably before the first shock) the shocks will go down and the compressor will come on to compensate. I don't think is stays on long.
When I added new Monroe shocks I used the air lines that came with them and added air to them at a gas station and left the line from the compressor hanging. When I put a load in the car, the compressor came on for a minute or two, then stopped, it didn't keep running, but it tried once in a while till I unloaded the car. After that I hooked the compressor to the shocks like it's suppose to be. Sounds like you got a hole in the line. Also my switch is where yours is, but the compressor is under the left front bumper behind a panel. You can see the black air line running from there to the shocks. If I had to pay that kind of money for a new compressor, I'd just cut the wires to it and add a regular air shock fitting and pump it up at the gas station when I needed to carry something.

My son suggested I get rid of the switch in the back and add a switch in the car to the compressor so you can raise and lower it anytime you want. Poor man's air bags!

The owners manual says the fuse for the Automatic Level Control is position #12 in the fuse box on the side of the dash. It's a 10 amp fuse.
