a/c and heat problems
 

my car is 2006 Dodge Ram 3500, 5.9L 6 Cylinder Diesel Turbo, My a/c and heat is totally messed up - the heat and cooling works properly but the a/c does not blow hard at all (tho I can hear it blowing inside the dash somewhere) - then no matter where the knob is for heat it always blows out the defrost (none on feet) - I have already spent around $1,000.00 and it's still not fixed - the blend air door has been replaced 2 times - any other suggestions.
if i want to fix it by myself does the tool nexiq 125032 can help me?

is there anyone can help me?

Off the top of my head I would say you have a vacuum hose leak. What I would call a secondary vacuum leak.

I agree with Tom.

i think try to this then get you result.

I'd look into the vacuum hoses as well. or is that one electric?

yes i agree too

$1000.00 Could you ex-plane that. Is that what you spend at a shop, if so I would take it back and make them fix it. Or did you spend a $1000. at replacing parts and guessing.:confused:

Check whether ice cubes are forming in a/c. I think that is the problem for your a/c.
