Okay, I have checked the clutch issue and I have read the sticky damper door thread but, non of these seem to fit my problem?
The a/c blows cold when it has a mind too but, in a mere few seconds it will blow like you turned the temp control to boil. go a little while then the a/c blows ice cold again. The compressor never misses a beat on the the back and forth.
Any help would be great!
I am headed out with the family for a 1500 mile trip in two weeks and a/c would keep the masses happy!

 

See the HVAC FAQs above.

 

That's a classic symptom of a broken blend door shaft or faulty Blend Door Actuator. Hope it's just the actuator, the new (possibly redesigned) plenum is pricy.
What is the vehicle?

 

Alright this is not a job for the weak!
I have began tearing the dash out.........damn there's a bunch of bolts!
I will give a update in the next few days.
This job is going to require many many beers.

 

I own two Fords 2001 F150 Supercrew Lariat 2003 Focus SVT.

 

well after many days a few hours a day it is done!

I thank everyone that told me what the problem was.....even though i didn't want to believe you!

 

I have uploaded pics of the dash removal and pics of the new blend door and actuator.

I have more pics if anyone wants to see them so, you know whether or not this is a job for you!

You'll find them in my gallery

 

Pyrodave how long did it take you to r&r the blend door and actuator. My pu. had the same problems last summer so I guess I will be doing this soon.

 

Sorry it took so long to reply!
I have not had email for about 3 weeks!
The over all project took a good 8 hours over 2 days.
chances are it is the blend motor and not the blend door.
that can be done without removing everything. It is accessible under the blend box on the hump. You can start there and try that first but, the motor is he expensive part and the blend door not so much. good luck if you haven't started yet and if you have completed it let me know how it turned out!

Dave, my truck is doing the exact same thing (and YES, I read the sticky above, but like others have said in the MANY posts I've read through about this problem, it's too vague to determine if it fits my situation) and seems to turn on the heat randomly and when I give it fuel or downshift, the air starts blowing cold again. It just started doing this, and living in AZ it's not as good thing to NOT have properly working A/C. How do you feel it's probably the motor and not the door?

I looked for the pics in your gallery but it says you don't have any.

 

projectSHO89 is the only person on here with over 5K posts all saying the same thing...Check the FAQ......WOW...SO much help

 

Yes, and I also WROTE those FAQs. They provide a lot of information that covers the most common issues seen on these trucks.

Gee, you just wandered in the door and that was all YOU had to contribute?

Good luck on your future projects. Perhaps someone else will take pity on you, but it won't be me!

I DID try the FAQ's but could find NOTHING that fit my exact problem. Except YOU directing everyone to the FAQ's. Everything I could find had something to do with acceleration and air coming through the defrost...I don't want pity...Or did I wander onto the Pity forum???
