Where is the fuze for the rear heat in a 1984 GMC SAFARI VAN?

I think that there is 2 solutions:

1. Check if there is enough gas.

2. Maybe you have to change the gas, maybe you put gas that don't fix to your car.

This rear end needs to be replace or re-built


































This rear end needs to be replaced or re-built. The gears and or bearings are worn/shot. May be able to get a complete rear end from a Junk yard for much less, one in good condition. Good Luck

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...

passenger side under dash. Your going to find two clear vacuum hoses have been knocked lose "likely by someones feet." simply reconnect the vacuum hoses together . Problem solved.
The blower switch is controlled by a vacuum line..
let me know if this helps....
