i have a 2002 dakota 4door, 2wd 4.7MPI, my a/c is freezing up. is there a cabin air filter or how can i clean out my evaporator cor without pulling it out. my blend door broke. how dificult is it to replace it. the local dodge dealer told me the whole entire dash has to come out. is this tru?

 

if the blend door is broken yes the dash has to come out.

I dont understand your a/c freezing up question. is the compressor freezing up?

 

Or you could have a low charge, did you check that?
