blower motor heat / A/C
So I am kind of disappointed in my blower motor. The car is a 96 with the automatic temperature controlled system.
The blower motor works and seems to get faster when I manually crank it up to 10. However, it never really seems to blow very hard. Now granted I am comparing it to two relatively new vehicles as a reference but this blower seems rather anemic at best. It does shift modes from vents to floor and mixed. Everything appears to be working in the system.
Does this seem normal to you or does anyone think my blower motor may be on the way out?
Are there any tweaks I can do to make it better?

in max A/C mode. So, maybe, the early C4s do not produce high air flow.
The fan in OP's 1996 should blow strong in max A/C. There may be a problem with the switch,
or blower motor.

My 86 was pretty pathetic air flow wise when I bought it. I actually modded it and got it working pretty good. The bad news is I don't remember what I did 
When I get to fooling with my 87's stuff more this summer if I remember what I did to the 86 I'll post it in here.

That is interesting, crowz. Owned vettes in the 60s and 70s, and they all had decent blowers. Don't know why the 80s vettes would be lacking in air flow.

The more I thought about it after posting that the more I think I put the blower wheel and motor out of a Cadillac I had in it. Im going to go thru some of my old stuff and see what I can find.

I apologize for the delayed response and thanks for all of the replies.
The blower does pick up some when switched to MAX A/C. The airflow does shift through all of the vents as selected by the controller so the system is operating as designed. My only concern is airflow from the blower itself.
Being in Maine, I mostly use the heater. With the top down and the heater on max (90) and blower on max (10), the air flow is less than dramatic. I can only compare this to my Jeep TJ in the same conditions, which could cause first degree burns.
Don't have another C4 to compare to here. My only other experience with a C4 was in Southern Florida where the setting was MAC A/C all of the time unless you were taking the early morning chill (60 degrees) out of the air.
So in short, I have no idea if all C4's have pathetic blower motors or if I am just the lucky one.
