Heat issue

[rusty ol ranger]

86 B2 Non AC

While i got it down for other issues i figured id look into this...

My heat blows piss warm all the time. And the drivers side blows more piss warm then the passenger slde. The cool warm selector seems to do nothing...even when it was 35 the other morning i set it to cold and got the same piss warm.

It also seems to let alot of air just blow in unless i close the recirc vent.

Im thinking it may possibly be in the mix door? Whats the best way to get to that stuff where the cables hook?

Any other suggestions on what it might be is apperciated

Loop the heater hoses when you dont want heat, simply unloop them when you do want heat.

Otherwise I would start by removing the glovebox and go from there to check the linkages.

I used to do that with rusty when the core would go to leaking lol.

By all means, if you want to go ahead...

The control head is right below the radio obviously so you may end up there anyway.

You may end up here too if you are really lucky...

FWIW- my '84 did the same. On mine, the blend door cable at HVAC control head had kinked, and forcing the hot / cold lever just flexed the kink and did nothing at the door. Once found, it fixed easy by straitening and lubing the piss out of the cable in the jacket and reassembling.

I'm not sure if your '86 has the same arrangement, cable-wise. I'm not sure what year started the vacuum servo controls.

And if I remember right, dropping the glovebox gave good enough access to the blend door.
