Hi guys, new to the forum and new owner of a 97 camaro, 6cyl, have been searching for this problem for a while with no luck. maybe searching wrong. Anyway there is no difference where i put the switch, blows out at defrost , have been searching for a vac leak with no luck but while chasing hoses I found this connector and took it apart and there is no vac at all. Is there supposed to be and if so where do i look next, thanks, capt

 

Changed this two way check valve that was cracked and clogged and it did the trick. I was not getting any vacuum at the fitting behind the glove box so I traced it back to here v, (a $4.00 part @ carquest)

 

thanks for letting us know what it was. i was trying to figure out what hose you were talking about and lost track of the thread.

 

It is nice when folks update their threads with their findings. That last post could potentially solve the same problem for another member.

 

I belong to a few different forums, and I look for answers just like everyone else, and if nobody posted up there findings , it would be just another chat room.

 

I finally got my dream car a 1994 Z28 convertible...now the fun begins w fixing all the little things that pop up for an older car. Im not mechanic by any stretch but i can follow directions. When my AC went out, I followed the clues to figure out what the problem was and ur post was the PERFECT answer to fix it!! Took me 10 minutes!!! Girl Power! lol Now I gotta figure out how to change the oil pan gasket!!! Thanx for the help and pictures!!
