if you have bad solenoid it will not support air to fan clutch , remove the hose that goes into fan clutch to see if there is air coming out, check connection to solenoid too , do not know if you have the same setup on cm2250 though

Update! After asking unilevers (genius) he right away said ac switch which is called hvac fan override switch which is located on top of ac compressor line that goes to condenser. Swapped it out $60 at stealership. Problem solved!! Thanks guys
