Well, really just blower volume. We have an 1984 Chev Blazer and an 1989 Silverado Pick-up. The amount of air the blower will move in the high position is kind puny…
Have seen this before in GM products.
So how can I get more volume? Is there a ‘super’ fan I can buy and swap with the factory one?
Is there a better squirrel cage?
Is it really a dirty coil in there that the truck must be dismantled to get to so as to wash it out?
We also have a little 93 Subaru Empreza that will blow your hat off. How to make the GM’s blow like that… ( Yes, that is a free straight line if you want it. )
Splain me please…
