I had some work done at ams awhile back (ems, cams, injectors, rail, and pump...and tuned) and everything went smoothly. Everything worked better than ever no problems anywhere.

Well about a month ago i had them install a gt30r and some head studs, and ofcourse another tune. well when i got the car back everything was working fine but the air conditioning. ???? well i had the dealership check out my a/c and they said, ofcourse, that it was my ems even though it worked fine before. well they manually tested if my a/c and the relay to the pump worked and it did, so now i dont know what is wrong with it...is the ems not sending the signal to the a/c to turn the relay and engage the pump? '


ps...by the way, the heat works fine and it blows, just not cold, and its not the refrigerant.

thanks in advance for input

 

im not sure about the ems, but if worst comes to worst, you could possibly just run a wire from the control straight to the relay or pump?

 

Why dont you call or go to AMS insted of the dealer. Im sure AMS could figure it out

 

sounds like u need to check and see if the relay has power to it and if it does u need to see if it is being to trigger to come on, if no trigger to come on then find out if there is a wire connection issue or issue with ems

 

Don't know if this could apply to you, but some EMS (such as AEM and GEMS) have an on/off setting for A/C in the software. I suppose the setting could have been changed by accident.
