Question about 1986 Toyota Pickup 4WD
Posted by Anonymous on
Check the hard wire that moves the heater damper flap, it often gets bent and will get stuck in one position, hot or cold. Commonly sheathed in a blue plastic ~1/8" tube. Both ends can get bent if there is excessive gunk buildup at the ends or on the lever arms (rust, dirt, dried soda, etc.) They also just come loose after time and slide in the pinch clips that hold them in place. Be VERY careful if it is bent and requires straightening. The wire is strong enough for a few bends, but don't over-do it!

You have one of two possible problems.
1) The temperature shaft retention nut is loose behind the knob
2.) The wires to the potentiometer part of the temperature may be broken.
Either one is common to this vehicle. The replacement of the AC controller is about 900 dollars. If the wires are broken, they can easily be reattached to the circuit board via soldering. What you would have to do is remove the control box from the dash, and disassemble it. Once the unit is apart, there are 3 wires from the temp knob to the circuit board that need to be re-soldered. The unit CAN be repaired, as opposed to the expense of replacing it.

i had a very similar problem with the emergency break light in my 1994 chevrolet k2500........
do you have a pedal......or a lever?
"""if you have a pedal...this is what you should do....
some pickup s like the c/ks have a emergency break pedal that in order to warn you that the emergecy break is engaged....
the break it self has to be away of a "switch like [clip]"... as soon as you dis-engage the emergency break pedal....the pedal will travel back to its original position and it will be making "contact with this clip'.....
why dont you take a look...."look for it, it should be located at the very front just under the pedal....."
if it isnt making contact...try adjusting it...."i think it is made out of copper...and it should be easy to adjust..."
i hope this helps.............

You can remove the dash fairly easily. There are a few screws (check by the peddles and open the doors and look there for screws). The rest of the dash just literally pops off. Once that is off you should be able to get to the ashtray/inside the dash to locate said item.

SOURCE: my 04 toyota rav 4 when the heater is on blows hot air out the center , right floor and right upper vents and cold air out the left floor vent and upper left vent. heater temp. control works, pos
Check your ducting and hoses going to the left side. Maybe one came loose.
Maybe a door towards left of heater case is not opening. Watch the cables for proper movement when operated. Maybe you can spot the problem. Good luck.
