Default Blower motor issue

I have a 1989 C-4 L-98 convertible. I recharged the ac, but it still appears the fan is not blowing very much air on the highest setting of 10. Has anyone else had any issue like this?

First, Welcome to the Corvette Forum Benjiumen!

The Expert in these matters is BATEE.Com. Bryan is the owner and he is an expert in those systems. He also rebuilds them. I would look up BATEE on You Tube and see if that has your answer.

Good Luck!

I did on my 85. Turned out to be the relay under the blower motor in the engine compartment. I don't know about the 89 system.

I've seen a few - including mine- with very blocked evaporators. Typical symptom has been very little air coming out of vents even though the motor works and changes speeds.
