a/c not blowing?

hey all, ive been noticing that my higher blower speed on the a/c didnt seem to be blowing how it used to and all the sudden the other day the blower just stoped working..i can hear a faint noise like the blower trying to work and some times i can feel very small amt coming out of the vents..my question is- is there a blower resister that may have gone bad,or it possible to be a bad head unit..im hoping its maybe somethin simple like the blower itself but its always more in depth than that it seems..im gonna ck it out this weekend and jus want to get a direction on which way to go............
thanks

No sure bud. I don't think it is the case but this happened to me. On regular ac the vents would blow pretty good. If I turned it to Max ac the vents would barely blow. I though It was a vacuum leak so i started chasing down lines. Up under the dash on the passanger side where the floor pan meets the firewall there is an intake vent. Turned out the vent was blocked by a plastic bag that had been sucked up to it.

Doubt that is your problem but worth checking.

There is a resister that is usually on the plenum chamber It will be like a small square with a screw holding it in place. the other thing it could be is the squirl cage has striped on the fan motor and you may need to replace that.

Mine had that problem twice and both times were caused by a vacuum line leak.

being that i only hear a faint sound from the blower im thinkin its more an electrical resister/motor problem..i thought the vaccuum controled the different selector doors to open and close on the evap case? i guess ill dig into it and check it out...

thanks for the replys

I'de say 90% it's the vacuum line. Mine made the shuddering noise and clicking. The reason why it did this twice is because the lines was routed wrong through the dash and getting holes in it.

thanks for all the help guys..it turned out that the 10amp fuse blew which might mean the blower is on its way out-maybe starting to draw too many amps..ill see if it continues to pop the fuse and go from there.

the vaccuum lines were easy to see when u pull the glovebox out and take the cover of the pass side under dash..good to know where everything is..have a good weekend all
