The check suspension light on my 99 Expy comes on everytime after 2 - 3 minutes from starting the engine!!!
The compressor works fine but it stops whe the light comes on.
What could be the problem...
The check susp light comes one even if I don't muve the car... and I think that it comes on even if I don't start the engine, I just put the key in the posision for starting!!!
What could be the problem... PLS help...

 

It sounds like you have the air ride suspension.

I'm not real familiar with what that light points to, but some possible issues are that there is a leak somewhere, or the compressor could be about to fail, etc. Its hard to say.

AutoZone might be able to read those codes but I am not sure.

More than likely you will need to visit the dealership or a suspension shop.

 

Thx for reply... the compressor already failed and haves been repaired....
I will visit the dealership but I was jus thinking someone already had that problem and could point me somehow.
