What Chevy Man can answer this ?

Here's the deal:

When using the A/C, low and medium speeds worked fine, but when switched to "high speed" the blower motor just stoped blowing (didn't blow fuse)

* I thought it might be the high speed fan relay so I replaced that, now when I turn on the A/C, low and medium work as before but when I switch to "high" it pops the fuse "20amp". (didn't pop when using old H/S fan relay)

* I assumed the new high speed fan relay was bad and returned it for another new one only to find it doing the same thing.

* I unpluged the inline power condensor to the blower motor and it still poped the fuse when I turned A/C to "high".

* I unpluged the blower resistor and still poped the fuse when switched to "high".

I haven't tested the control panal in the dash yet, but was wondering if anyone had any other good ideas ?
