Blower issue

[Fishfan]

So, I just got my 66 Polara 318 Poly back from the shop. They replaced the evaporator with a unit from original air. Now the blower seems to be blowing much less powerfully than before (on all three settings: low, medium).

Any ideas? Faulty install? Something electrical?

There's a Bruce Jenner joke in there somewhere....

Check your hose connections for the discharge air to be sure they are all tight.
Blower motor might also be failing, also check the gaskets on the air box for leakage.
