thats the first and most times easiest check. After that, in my chevy's i always take the control panel off and check the wiring pigtails to see which ones have shorted out (usually just behind the switch). Thats chevy, but an easy check also.
After the easy checks, you'll want to check the valves which, on my mitsubishi's have been inline with the heater hoses. you may need an volt/ohm meter and the appropriate values for a functioning valve. it could also be a physical deficiency. you can take the valves out of the car and check them too.

Let me know how you make out!

Hi there,i have checked the heater core and the hoses and they are ok,and also the heater switch inside the car.I also put a new thermostat in as well,the next thing i was going to do was the inline valve on the heater hoses. thank you for your advice

well like a week after i first posted, the heat decided to start working again. but it would only work when i first started the car, if i started it then went and got gas or something the heat wouldnt work when i restarted it. as of 2 days ago im back to no heat. But, looking under the hood the other day i relized the heater control valve wasn't opening. so i manually pulled up on it and volla, heat. but... it wont stay open. when i let go it just closes back and its not easy to open. i messed with it for bout 1/2 hour but it wont stay open, and i have a blister on my finger. do i just need to replace that controle valve (crossed fingers) or is it something electronically telling it not to open. oh, and yea it does make that weird rushing water sound, and all this time i thought that sound was normal, lol. thanks in advance for your help guys.
