problem #3 in my 1998 ranger
when i put the key in the ignition and i have the fan setting on at least 3 i hear one of the door slap which i am assuming is the blend door? anyway my problem is the heat usually works if the door pops open,but when it does it is hot hot hot. the temp control doesnt work. how can i check if the switch works or not? i cant have it on all the way cold or all the way hot and it just stays on heat, but the fan speed control works and the other switch works to control whether it blows straight out or mixes floor or defrost, so i am assuming its the swith, or hoping anyway.. thanks in advance

How does MAX A/C work? If it works, then it's prolly the blend door.

LACK of heat on Max AC only, would confirm that indeed you blend door is shot, although it sounds pretty certain. I did the "fix", lasted a few weeks and broke again. I can live without the blend **** at this point, I just use the windows more. Max AC should give you cool air in the summer, but like your current situation, you cant blend it.

Re: Blend Door Fix
Very cool..thanks a bunch for the clean link, I brought it up and was able to look at the pics. I went out and did exactly as the instructions said. The actuator doesn't snap fully back into place, but....I have heat!!!! I'm in Central Mass where it's been 15 degrees for the past week so this helps a lot! When I first turned the actuator dial from cold to hot I heard a clunk then I had heat. When I go back to cold it stays hot. But that's okay!!! I still have cold air in Max AC so that'll help in the summer. Thanks again!!!

Blend door fix
I did the blend door fix with the pin. Did not work. The accuator did turn the broken top of the blend door 90 degrees, but still hot only. Is the next step cut the bottom out and replace with new blend door? Or maybe the a/c comp relay switch is the problem?

i only get full stream of air through the defrost ducts (close to the windshield) and not through the main vents (regardless of A/C or heat setting) Is this the same problem that's described here????

Here's another thread with information on the climate control air flow system:
