The vehicle is a 2005 GMC Safari. Is the part you mentioned still the correct one? Also, there are several parts shown on the break-out diagram. I am assuming the most external part is the one I want e.g., INSULATOR,BLO(INLET)(ACDelco #15-80799) on this breakout diagram: http://parts.nalleygmc.com/s...

I have a problem. The housing for the blower looks to be heat-fatigued. It is all cracked and brittle. I can barely touch it without more pieces breaking off. The part of the housing that covers the AC condenser (?) is also in the same condition. Has anyone else had this problem? How did you resolve...
