Is the heat-air controller in a 97 Olds Achieva electric or vacuum and where can you find a schematic?

On my 1994 achieva its vacume controlled i had to replace the line going to the controller. It was broken. It runs frin the top of your intake throttle body its a small line maybe 1/8 inch down to a vacume tank in lower front drivers side, from there it runs up the drivers side fender accrossed the firewall towards the top and into the passanger side through the firewall. It comes though behind the glove box and over to a vacume spliter behind the vent selecter. mine broke right at the vacume spliter. Word of advise use heavy stiff plastic vacume line to replace it anything less will colapse when vacume is applied. this solved my problem. the line is very easy to replace.

What do you think the problems is When your 97 safari heatair fan will not work on any speed?
your blower motor resistor is probably bad....it shoul dbe replaced.
Does anyone know what operates the door to allow air to be tranfered to head mid range heatair in a 1977 corvettei know it is not the vacuum system because it operates the defroster but the mid range?
I have a "77" but have never heard of head mid range heat air. I have had the complete dash out and all heat and air functions to my knowledge are hooked to a vacum system.
