I'm Awesome
Hi folks,
1997 K2500 Extended cab Silverado
For a long time now I have noticed unreliable operation of the mode selection (Defrost, Floor, Vents). Sometimes after a while I'll get the mode I want - usually the defrost/floor combo. Where it really showed the problem was trying to get good flow through the dash vents in summer. Sometimes when I start the truck I can hear a bit of a thump as an air door closes (or opens). Sometime the flow will increase or come out the right place after I've been driving for a little while.
Last spring I had a new compressor installed and that gives nice cold air now.
Now in the dead of winter I get nice warm/hot air so the heater core is doing its job.
The real problem with all the above has always been the lack of airflow. I changed the blower motor/fan yesterday. The old one started making some dry squealing noise for a few minutes when first started cold. The new one is nice and quiet and smooth running. When I first tried it yesterday after install I got good airflow to the floor and OK airflow to the windshield as selected.
Today, however, I am getting very little airflow anywhere. It does seem to go where directed, but there is so little it likely won't clear the windshield or heat the truck.
I am hoping I have a couple of worn out mode/blend motors, but NOT the one that requires the removal of the dash. I do know the recirc has always worked as it should.
When I had the blower motor out yesterday I did sweep my hand around inside the heater box and it was clean - no leaves or crap to feel.
So, can anyone give me a reason to continue living?
Thanks,
Glenn
