Default 91 silverado blower motor.

I have a 91 silverado 1500 extended cab. Blower motor works in all modes, just does not blow much air. Been told this is characteristic of this model. Any suggestions?

Thanks
Mark

seal on blower box might be bad in which case all the air is escaping before getting thru vents. or flapper door is stuck.

Default Blower Motor air leak

Thanks for the idea. I will check it out. I also thought about pulling the blower motor out and cleaning the squirrel cage real good. I will let you know how I make out.

I had a similar problem, when I removed the blower the coil was completely clogged.
cleaned off the face and air flow was restored.
good luck.
