Hey guys ,im in need of some input! how do you blow smoke? ( JUST KIDDEN) i have a 03 X and im not getting vent blowing out of any thing but the defroster vents! Its digital controls and its all working , biut it doesnt go from defrost to vents to feet mode , it just stays up on the defroster? i checked the normal vacum hoses and nothing pops out at me but i didnt know if anyone else has had this problem? HELP
i had the same problem last fall and the EATC head unit had to be replaced..mine would struggle to actuate the little doors, and never make it to the dash vents..
Turn key on and make sure the vaccum pump is coming on. The pressure switch that controls them inside the pump likes to stick on and burn up a fuse or off and it won't come on at all.
If no fuses are burned out, and you have good vacuum to the EACT head, you will need to remove the EATC head, pull the big plug of 6? vacuum lines off, get a vacuum pump, and apply vacuum to each line and see if it changes to vents or floor, this will make sure that the mode door is working properly and isn's broken. if you can get it to go to all the different modes with the vacuum pump the EATC head will need to be replaced.
Thanks to all you guys for the help, i ordered a pump unplugged the old one plugged the new one in and it worked! now everythings workin, i even capped off the line to the front dif. Once again the NATION came threw!
