Not shure what heating coil you are talking about but you could have a bad heater control valve,a plugged up heater core,or you could be very low on water.

My cold/hot knob on front dash clicks when i turn to hot


Look under the dash above the gas pedal and switch the hot to cold knob back and forth. you will see a cable hooked to a white plastic cam, this cable usually pops off the black plastic housing and causes this. If it is connected there it is in the control knob itself.

No heat / heater not working


not blowing air or when switch is on blows cold air when you have climate control knob turned over to heat? it could be a switch or blower motor or fuse if its not blowing any air. if its blows cold air when knob is on heat then is can be thermostat or low on coolant or it could be climate control module or it could be a air filter in dash.

Shifter slide cover separated in my 2004 merc sable. The back section did not slide back out. How do i get it back, and how do i stop it from happening again?


The solution is to replace the little pieces of plastic that slides back and forth.You will need to remove the shifter knob, then the part of the console that allows you to work on the pieces needing replaced. You might get it to slip back to working again but it is going to need replaced.

2003 HONDA ODYSSEY VAN WILL NOT HEAT


Your problem might be that the Heater valve(located under the hood by the back wall, circle in blue in the picture) is not opening.
-Have someone turn the temperature knob inside the van slowly back and forth from hot to cold.
-You should seen the cable(letter B) (note:cable should be connected to lever on top of valve letter C) move back and forth as the knob is being turn.
-Check to see if the screw on top of the valve(color red on picture) turn back and forth will the cable and lever.
-if the screw turn very little o not at all. Valve is bad and need to be replace.

The knob for the heat turns but do not switch over to heat


The cable that flips the heater valve has become bent and will always bind until it is replaced. If twist the knob back and forth gently you can work the knob over to the heat side . The bad news , it is easy to turn the heat off , but it will be tricky to finesse the the heater back on again.

The heat/a/c controle swich is hard to move. It seems the heater box may have a flap inside of it that is hard to move. what is the fix. what do I have to do to repaie it.


Mitsubishi uses cables to operate the flaps and heat valve. If one of the cable wires gets bent or kinked it is always going to be hard to move. If you are careful and gently (wiggle back and forth) turn the knob you should be able to use it till you can get the cable replaced.
