Heater switch will not push over to hot

1991 honda accord heater switch will not push from cold to hot.m It pushes over about 1 inch and lams. It feels like something is stopping the flat from opening/closing all the way. I do not know how to get into that box where the flap is (near the firewall), to see if something is jammed.

No air coming from vents

good the blower works.
it takes 2 more things,
1: hot water, (engine coolant ) at 180F or more holding.
if not fix that first.
2: water flow , if both heater core hoses get hot 180F then the core is hot. and means,
3: no air flow through the core,
dampers failing, or controls. to them.

The heater doesn't work. The air just work get got enough to defrost the the windsheild. What can it be??

the most common problem i've seen with these accords are the Hot Water Valve. most likely it is stuck in the closed position, not allowing hot coolant to enter the heater core. You can manually push/move it to the open position. Its under the hood on the heater core inlet hose.

No heat on 2005 honda accord - air works fine but its cold here now in NJ.

My did this recently. I went into the engine bay. Directly on the middle of the firewall you will see the heater core hose coming off the firewall going to a plastic boxy thing. That thing has a thin black "cable" going to it. It looks like the cable for a bicycle brake. This cable attaches to a metal prong. That prong regulates the hot coolant that goes through the heater core to heat up the air.

Go ahead and push down on the prong that the black "cable" attaches to. It should push down about 1" with minimal force. Dont go putting a million pounds of force on it.

Thats what I did with mine and it stated working. Post up if it worked!

The heater valve is under the hood that lets the hot water into the system where the hoses go into the dash you can push it open with you fingers when its cold-is best, and the mixing door runs off a small motor, Its under the dash on the left side of the center console look around under there you can move them manually too and watch when you turn the switches you should be able to tell which motor or the switch is bad, either way you should be able to manually get the heat on.
