the Ac compresser doesn't come on when button is pushed the blower fan works high and low.tempeture works high and low but the blower air only comes through dash vents not on the floor or defrost no matter the posisition you use.
heater/Ac has a problem i think it's the climate control on 2003 Mercury Grand Marquis
SOUNDS LIKE YOU HAVE AN ACTUATOR PROBLEM OR VAC LEAK
what is an actuator and where is it located after checking the symptoms for the actuator it doesn't sound like that. I have no problem with the temp just the other buttons and the air flowing through Ac vents. and no wired noises.
the act. are located under the dash and they open and close to regulate the proper air flow
how do i check to see if it is the actuator and how do i remove it. but would this keep the Ac from comming on?
they are complicated to repl and diag at times see you mech
