It is likely the compressor for the air ride leveling system ....... if it is running excessively you may have an airline or airbag leaking....or one of the sensors are telling the system that the vehicle is not level. this is probably not a repair for a novice but if you are handy you could find a manual that explains the system and it's components and hopefully some trouble shooting options
hope this helps.......thanks for choosing FIX YA!

Pannel 1 is under dash on drivers side cover pops right off, Under the hood there is a big block fuse / circut breaker and reley center located oh the fire wall, under a plasti cover .
