My 1993 Z28 camaro blows strong air but not cold in summer and defrost will not clean the windows. What could be the cause of this problem?
My Camaro's are all victoms of the air flow control vaulve. My 77 had a cable that phyisically opened and shut off air flowfrom the heat and cold side and operated as I moved it from cold to heat. Then they came out with Vacuum assisted air control units that when the rubber vaccum tube dehydraded, it would be stuck in what ever it was in last, say A/C, or if u had the heater on that day. You have either cables or air hoses that open and close certain doors under your dash according to where you place the enviromental control to. 9 times out of 10, that control mechinisim froze up, a plennum door could have broken off leaving that area always open and the heater is always off. Check the book, im not 100% but it may be all electronic in the 93's if so, first check your fuses. Also check the passenger floor board for dampness. If the passenger floor board is wet, then your heater core ruptured also. It's a mini radiator under the pass. side dash. But the real deal is the air vents that open and close according to your input are not moving at all, and if they are electronic well Don't rip the dash out, that is a pain to reinstall LOL, Best bet is to take it to the chevy house because if you get the book, u'll see theres quite a few moving parts and with old plastic and them dehydrating, you can easly brake a door control and make matters worse. Good luck.
