Wtf - Does Any Body Know?????

[MEWKS]

Ok so where do I began? I just had my intake manifold gasket replaced, I then noticed a cycling (motor,moaning,growling sound) coming from the dash? I turned on my heater (climate control) and I recieved hot air then cool air also cycling through!!!!! So I turned on my A/C and the same thing!!! I found the vacuum hose from the intake to the res tank was disconnected so hooked it back up, but still had noises? I have it it the shop now since I ripped the dash apart and couldn't figure anything out after searching the internet and all auto repair books (can't find any vacuum diagrams nor any information on anything in the dash besides the dumb heater core) Does anybody have any idea of wtf is going on????

+ changed gasket, therm, and flushed heatercore!!!!!!

Thanks for any knowledge that may help me out!!!!!

Sorry I thought I had wrote it!!!! 1999 OLDS Bravada w/ a 4.3l Vortex V6

I'd start by recalibrating it. Pull the RDO/BATT fuse for about a minute, then put the fuse back in. Turn the key to "On", for about a minute so it can reset.
