plz for the love of god HELP!!!

ok so i got this 91 chevy and i have had this heater problem with it since i bought it like 1 year ago, where no matter were i set it to blow out (defrost or floor) it always comes out of the face vents as well.Also i hear this kinda buzzing noise when i accelerate is this conected to my heater or a new problem??
I think it is a vacuum line but i dont know were to start. I dont know what to do and it is bothering me because now i have a code #32 flashing at me and when it comes on it really kills my milege!!! Is this connected??
And i really dont want to pay for a fix i can do myself.

thx for any help

Por favor, use the correct forum... they might be able to answer your question over in C/K

32
EGR open command did not change MAP sensor signal. Normal EGR flow should cause slight decrease in manifold vacuum which would change MAP sensor signal.

This is not connected, at least I don't think so....I have seen some things that make you scratch your head though....anyway....I think these heater systems are electronicly controlled with motors and wires, not the old vacuum lines. I would say that you have a bad damper motor or a bad connection, again this is all guessing....i think.

so u figure my EGRs fucked??

not necessarly could be much worse... or better (but I doudt it). egr on a 91 i beleive is a negitive pressure type , which is easy to get at and can be tested with a vaccum hand pump (like a mighty vac). someone back me up because i'm totally guessing right now. Oh and I would not statements like you did above, I think the moderator will not like it. I know we talk like that every day but I don't want to see you get banned. At least until you get this fixed.

ok ill watch my mouth, , thanx ill check it out
