Air conditioner works on both sides, cold air
Heater only blows heat on passenger side, blows cold on drivers side

what is is there is a door that was designed for dual climate control inside the dash....even if you may not have dual climate control you still have the door for it and it fails...it takes at least 8 hours as you have to take almost the whole dash out to get at it

it is not the blend door .the blend door controls the blending of inside and outside air intake only.

I had the same problem Iwas told by dealer ship that they have problems with t he blend doors braking inside the heater box wich you 'd have to remove the dash. I removed my dash and heater box to find nothing wrong.But what I did find was that the heater core was clogged. you don't have to remove the dash to flush it, remove both 5/8 heater hoses going through fire wall under hood use a garden hose to back flush heater core DON'T USE FULL PRESSURE spray into 1 side of heater core until water runs through freely then do the other( back and forth) then this should fix

i tried this and it didnt work . took dash out and checked all act.doors couldn't find anything wrong . ac works on drivers side not on passenger side .just the apposite on heat
. i will say that once your on highway for a bit you start getting some heat out of driver side.

this millenia chevy truck having same problem, thought some internal control problem, but will try the hose flush, even though I don't see why both sides aren't affected the same way.

yes I had the same problem on my 2002 dodge ram took the dash apart removed heater box nothing was broken, the heater core was half clogged,the way it sits in the heater boxd, the front 1/2 of the heater core goes to the pass side 3 vents the other 1/2 goes to drivers 2 vents,I have single zone heat in truck but all dodge heater boxes are universal for both types of heat dual & single zone. I would suggest before removing the dash, remove to 5/8 heater hoses going to heater core under hood (fire wall) and back flush heater core with garden hose NOT FULL PRESSURE spray into heater core 1 side than the other back and forth till it runs freely. my hoses were hard to get off I had to use razor blade and slice hoses the long ways to get off theres still enough hose to slide back over and clamp,also i do agree with other people the blend doors do break but it sounds like you have the same problem I did bleading the air out took a little while KEEP AN EYE ON TEMP GAGE AND COOLANT LEVEL after starting.I've never had my heat so hot since i've owned this truck

i have the same problem in 2001 mitshubishi eclipse

Thanks! This worked for me too! Although I'd like to add that you can just remove the heater hoses from the closer ends instead of at the firewall. This way you can more easily get the water into the hoses. This whole process only took me about 15 minutes, and my heat is like NEW AGAIN! Amazing! I'm sure a repair shop would have gouged me big time and said it was a heater core or something expensive. Thanks again!

I'm currently having the same problem with my 2003 Honda Accord. I hope with what is said on here it will fix my car as well im tired of not having heat on both sides. Hopefully I wont screw up anything because I'm completely new at this but its better then spending more money which I dont have. Thanks again
