Re: Blend Door (with pictures and the common problem)

I had heater issues...tried changing accuator (thumb wheel extension on 7/32 socket made removal a snap...) ended up being clogged heater core spent $140 to find out it was a 5 minute fix and free also! Make sure heater core is not clogged before changing accuator

Re: Blend Door?

On my 97 Blazer everything in the a/c system is new, even the blend door motor and I still have the same issue. When it's overcast and the sun isn't beating down nasty hard, I get pretty cold air out the dash but not spectacular. But when it's blazing hot, it's barely a whisper of medium cold. If that's a measurement. Is there a certain timing for the blend door motor gear that I didn't get line up correctly? With 38 on the low side and 185 on the high side and the accumulator will freeze your hand, what's the problem, does anyone know?

Stressed!

Re: Blend Door (with pictures and the common problem)

If it's 90 outside, 140 inside what do you think the ducts are? Sunshade cover. Step daughter complained that her a/c wasn't blowing cold enough. She never put the sunshade in place. Next time she stopped by. I put the sunshade up, waited around 4 hrs and drove it around. Pretty cold. Get a meat thermo and see what actual temp is blowing out the vents.
