Happy First Sunday of the Oktberfest Gentlemen! PROST, from Munich! (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/smilie_flagge6.gif)

Curious about this almost comical "instruction on our ventilation controls..."MAX DEFROST, upper levels left, lower lever right"...I was thinking, how is this correct, when the upper lever left turns the blower onto the windshield OFF?!

So I found this thread...

http://www.914world.com/bbs2/lofiversion/i...php?t75480.html

and then I went out and tested to see how much warm air from the back is actually blowing out of the vents at the windshield. Virtually NONE was coming out at all.

So...before I go seeking the possible reason, I'm curious about others' results for this same test. What is the best / normal (stock) result here? The hoses in the compartment were OK. I haven't checked those under the car or the dash yet.

How much more effective would a stronger blower be? Power / spec suggestions?

Thanks guys, and have a great Sunday!

In my experience you should be able to noticeably feel air coming out. That's about it. At its best it's not going to blow you away like the max fan setting on a modern car. I actually took my blower out after futzing with it and trying to optimize the volume of air it would put out. It clutters the engine bay and I get enough heat/defrost from the engine fan.

Having said THAT...the teener has been relegated to outside the garage to make room for my wife's car. I drove all winter last year, but it's going to be a different story with the car starting outside and exposed to the elements in the winter mornings... (IMG:style_emoticons/default/dry.gif)

Sounds like I need to check the tubes. The air isn't getting into the cabin the way it should. So, my HEAT should be really BLOWING onto my feet, instead of "drifting" (light blowing) into the cabin?
