replaced air suspension compressor but it won't come on!!

when I hit ur link it gave many options but I did'nt c a tsb's, lol I'm a little green but wut is a tsb?

i replaced it because pump was locked up, I put it in and it isn't responding but I used wire straight to battery and it came on. Trying to c where to go from here, and where is the height sensor? Do u know exactly where the relay is?

height sensor located on rear suspension. relay located on body behind right inner fender.

do I need to take off the tire to get to the sensor? I had found the on and off suspension switch in the back kick panel

should be near center of rear end.

thanks checking, and do you know where I can find relay mounted under front? do u mean under the hood? I checked #27 5A*- air suspension module ( run/start sense), #30 25A*- air suspension module ( air spring solenoids and height sensors), & the #111 50A*- air suspension compressor, air suspension compressor relay they all looked OK. still trying to locate height sensors in back

relay is 2"x3" with fins on it. about 1" thick. has a flat 4 wire plug goes into it. does not look like a square relay. is flat. has 2 screws holding it to body between bumper and right inner fender.

thanks for all your help, i'm checking. how do u get to it? I Really appreciate all the help. Come to find out it was the Driver side air suspension Sensor wasn't connected! Wow!! It's Rolling like Silk!
