vacuum line off the mode doors probably. probably wasn't hooked up near the firewall

quite possible


do you hear the blower motor working, just feel no air movement?

 

[saleenjames]

no i dotn hear anything. no matter how high or low u turn the fan onto. u can feel a lil coming out when u put it on the defrost though.

might be a blower resistor issue, or a power feed issue(you check the fuses?)

 

[saleenjames]

checkd them all

Follow the vac line from the brake booster to the firewall (passenger side) and under the dash. It will be broken somewhere (possibly more then one place) Another test is to unplug it at the booster and apply vacuum to see if it holds pressure.

The blower motor would still work on hi only.

The blower motor would still work on hi only.

which is why i also said it may be a power feed problem

 

[1BADAIR]

unplug blower and apply 12 votls

maybe bad ground

Shouldn't be a power problem as it comes out slightly in defrost mode. Will be vacuum related
