I have a 91 integra.

The left vent doesn't blow as hard as the two middle ones when the fan is at the highest level.

Do you guys have the same issue? Or is this an engineering flaw by honda? Do you think I have something clogged in there? Is there a quick fix on this thing? thanks guys

 

Hmm, I never had that problem before. If it still blows, probably something is clogged in there. Im not exactly sure how to fix it though

 

anyone else have a comment

 

I have always had that problem on my 93. I just figured it was a flaw. The sides always blew less intensely as the middle ones.

 

Ya I guess it is. Being close to the blower motor, it should put out more air in the middle. Ohh well , thanks guys.

 

Hey mate. New member here. sorry to hijack your thread but i thought it better to post here instead of staring a new topic. I have a 1990 EF9 Civic and i have a similar problem.
What happens with mine is that the heat only comes out of the vents closest to the windscreen (dehunidifier). When i change the direction on the control cluster, it doesnt change the direction of the flow!

Any ideas as to what could be causing this?

Thanks heaps guys.
