so I bought atticus925's twin turbo about a month ago.
And I've been trying to figure out why the heat will not turn on.
He put a new blower motor in it and everything.
I can hear the vents cycling from floor to face to defrost.
Just no air comes out. I can't even hear the blower motor turn on!
I checked an replaced all fuses and relays relating to the problem *at least to my knowledge*
The car was hit in the front and caused alot of damage but was repaired so i don't know if something was broken or taken out relating to this issue or not!
I really need the defrost to work so I can drive it to work some days :)

Help me PLEASE!

I don't, but the FSM may have a wiring diagram.
