Question about 1997 GMC Safari
The rear heat and rear AC will blow out but it will not work .....
Two different problems !
Rear heater problem: find under the hood where is hose for cooling liquid goes to front heating core!
you will see there also vacuum tubesgoing in to little valve ! disconnect the vaccum tubes ( engine off)
and spray in wd 40 in to the vlave ... valve is stuck and wont open flow to rear heater !
you do not have to replace tha thing . its very well made and because you dont turn this often in summer
it gets stuck. i had same problem. also make sure vacuum is working - Engine running turn rear heater on - vacuum sucks to open valve. and before that make sure fuse is ok .
for rear AC mine does not work either and it is leak on pipes that go from front to rear .. 10 feet of pipes and tubing $$ expensive repair ... forget it ... open the window...
