87 Honda Accord heater problem

Not sure if anyone has any advice for me on this but my son has an 87 accord and the heater control doesn't seem to do much until you slide it all the way to the right to set it to HIGH. Then it blows full blast but there doesn't seem to be any middle ground.
Not sure where to look other than start peeking under the dash to see if something can be adjusted.

TIA.

Your cheapest route maybe to get a new heater control unit (where you adjust temp,speed, etc) from a junkyard. If that doesn't solve your problem, then you may have to tear into the air box.

Also, does the controls work correctly for the A/C if he has it?

No A/c

No A/c in this model.
So the heater control unit... would that be something under the dash attached to the back side of the dashboard controls?

Try replacing the actual controller. The part that you adjust the temp on and fan speed.

Ok. I guess I'll take a trip to the junk yard and see what I can find.

blower motor resistor

This is one 'late update for the archives' but I was doing a search on 'accord' and found an old posting of mine but not the solution.
It ended up being the 'blower motor resistor' that sits at the bottom of the heater. Found one at the junk yard for cheap and it's worked ever since.
