so since it was 50 degrees I thought I would give my air conditioning compressor a good run, now here is what I do not get, when its down on 60 degree it blows out the vents fantastic..but when I crank it up to 90 degrees it gets restricted..what is the deal? do I have to take out the glove box to get to the controls?

Maybe the heater core is clogged up?
