Mitsubishi Repair: No Heat???, climate control, heater core

Question
Last winter I noticed a clicking noise under the dash when I switched the air from cold to hot. Now I don't hear any kind of noise but when I switch the air to hot, I get no heat out of the vents. I changed the climate control panel out but it still won't put out any heat. What do I do??? Please help...Steven

Answer
Steven,
This sounds like either the vent that opens up to allow the warm air from the heat core to enter the cabin is not opening or there is something preventing the coolant from entering the heater core all together.  You may need to have the heater core pulled and inspected.
Good luck!
