I'm trying to figure this thing out and I need help. I just recently cleaned out my throttle body with the advice I found with this site. It fixed the issue I was having. However now my A/C stopped blowing. There seems to be a draft coming through the vents but its real faint when i turn it on. I have over 120k on my 2005 f150 5.4 2wd triton. Never really had any real issues til now. I live in the desert so the A/C is not a luxury, its a nessecity. Any advice before I pay someone else to do it will be appreciative. Thanks again for this wonderful forum!!

 

if your only getting a faint air flow out of your vents when you turn it on i would say you have a blower motor issues. make sure its plugged in and the resistor pack behind the glove box is good. when the resistor pack goes bad you generally loose one or 2 speeds and have high speed.

 

You may also want to check your blend door actuator. Although if messed up would only be stuck in one direction (hot or cold, shouldn't really affect air flow), but it might've done something in there.

Also it might just be the blower motor itself.

Just giving suggestions.

 

Thanks for the suggestions folks but i tried replacing the motor resistor and had no luck. Everything seems to be plugged in pretty good. Ill keep researching and will post here if i find something that could possibly help someone else.

 

have you checked your fuses?? do you have power and ground to your blower motor?? if so probably blower motor.

 

Also, check you didn't pull a vacuum line out by accident.
