Since the cab of the truck is small I usually just leave the defrost on and that does fine with heating the truck as well. A couple of weekends ago, I had the temperature on heat and moved the selecter to the vents. I don't know if the lever broke but I tried to move it back to defrost and the vents stayed on and I can't get anything out of the defrost. I can not move the selecter all the way to the left now as well. Any ideas if there are any clips that might have broken behind the vents? Ther is not much room and I have not been able to figure out how to take the dash part off to get behind it.
Any help is appreciated!!!!!!!!!!!!!
Sounds like the cable was binding..then either broke or popped off the metal tab. Difficult to tell unless you pull the selector assembly out.
Haven't worked on one of these in awhile...can't remember the dash layout.
If you look around the air ducts behind the stereo area, you may find the vent "doors" and their cable attachments. Move each control on your dash until you find the one not working...then move it by hand (you may need to undo the cable) for a temporary fix. Hard to troubleshoot not being there.. sorry.
I think the worst part of these truck is the limited room behind the dash if you have to work on something, unless you want to take the dash out everytime. I will probably look at it again when I go the the camp this afternoon. If I have any luck, I will update.
hey, just an idea, I have had selveral trucks that the heat only works on the floor/defrost and defrost mode, they will not put heat out of the dash vents, mine might be broken?? I don't know, but they will heat from the floor
I had a similar problem on a 92 Suzuki. The cable to the temp control lever had bent just behind the lever. The control door on the heater core housing was stuck and the cable kinked because I "forced" the lever (it did not take much "force"!)
I removed the entire dash to locate the problem. But I was able to straighten the cable and free the door and the problem is solved.
I hope this helps,
Daihatsu's do send heat out of the top vents. At least mine does anyway, and it's the S110P chassis.

My HiJet is a '94 S83 chasis. Last week after not finding anything broken, I was able to get the lever to move again. Below freezing the next morning and the defrost was workign again. I assume mine will not blow heat out of the vents, and the lever was just stuck on the vent selection. I did not do anything other than get ticked off and hit the dashboard and the next thing I know it's working again.
