My '94 GMC K1500 Z71 4x4, 54k actual miles -- Air conditioning/heat louvers and defrost outlets seem to be stuck. I get a little air going through the defrost vent on the dash, the air vents on the dash, and a little coming out of the floor vent. No matter how I move the instruments I cannot get much air flow. Blower seems to be working fine, just can get the air to come out where needed.
How do I check this? Do I need to removed the dash? Are there vacuum hoses that control the louvers?
have the same problem?
