2000 eclipse heater - swithch on HOT, doesn't put

make sure heat temp. control pot inline on one of the heater hoses is functioning properly by looking at it while someone inside the car is moving the selector switch slowly from cold to hot several times, you should be able to see or feel the valve moving. if not, check for vacuum at the pot by removing the hose from the pot and holding your finger over the end of it, you should be able to feel the vacuum with your finger. if there is no vacuum check the line for cracks/dryrot, if theres none the switch is prolly bad.if the pot is working make sure coolant level is full, if it is low there wont be sufficient hot water pushing thru the heater core

2003 Mitsubishi Eclipse GS blows cold air in heat mode.

ok here we go and you aren't going to believe it...
I replaced the thermostat step one

I noticed that I had a small leak at the engine side of upper hose fixed that by taking it off and cleaning it and putting the hose back on Step two

then while refilling the reservoir with coolant i found that the hose that was supposed to be in the fluid was curled up on top and not sticking down in the fluid where it should be.
played with the hose until i got it to fall down in the reservoir where it should be Step 3

I started the car with the radiator cap off and let it run until it got to normal operating temp. and keep filling the radiator with fluid until the level stayed constant. Then put the cap back on and test drove. Everything worked fine haven't had that much heat in awhile and it kept blowing hot even when i stopped and let it idle for ten min.during test drive. Checked reservoir when I got home and had to add a small amount of coolant but not much.

I really think that the hose in the reservoir not being in the right place and pulling air into the system instead of coolant is the real culprit of this drama, but i replaced the thermostat to be safe.
