I posted before on this problem and have done a lot to try to fix it.

Today I pulled the dash out to replace the heater core (leaking) and while I was there i traced all the lines and checked everything.

I have great vacuum in my dash at the grey line. I have vacuum at the "t" valve, pulling 20 from the truck to the "t"
20 from the the 't' to the vacuum canistar. So point A the motor to point B the controls have vacuum and hold it.

I can control the fan speed, I can control the heat/cool settings.

I just can not make it go to the vents or floor or have a/c.

Now, with that said, the 4wd. As stated I have great vacuum. I can hear the motor on the trans click to engage.

If i am in park and push the buttons hi or lo I get a flashing, so i just put the truck in neutral and pops right in.

If i do a brake test my rear tires just spin. I have the lo and high gears when i do it also

I have checked all fuses (in the dash)

Will the a/c not work cause say low charge make this happen? I just hear my a/c clutch ready to blow from not working.

I let it run and shut it down for a few to enjoy the cascade bath to get out any oils and stupid stop leak stuff the past rocket scientist used. Yes Cascade the dish washer stuff. I am going to run to the auto zone and pick up a steering wheel cover and engine cleaner.

the truck in a 1994/1995 vin says 94, door says 94, under the hood says 95. (Has the old school head lights if that helps)
4.3 ltr
4 door
slt
green w/grey cloth interior
31X10X15 tires on stock rims that rub the fender on driver side
dent in passenger door, I just popped out
tinted windows
no radio (thrown out the window in the summer)
no alarm (just ripped it out when i pulled the dash)
3 kids car seats
1 busted fog light (not even hooked up)

I just added all this just incase
