Problem with 1996 Mazda Protege AC/Heater Control Unit and vents

I have a 1996 Mazda Protege. I am having a problem with both my vents and my AC/Heater control unit. First off, the only vents that air will come out of are the front/rear defrosters and the driver side vent. No air will blow out of the middle vents, the passenger vents, or the feet vents. If I put my hand up to those vents I can feel hot/cold air coming out but it is not blowing out, it is only hardly seeping out. Even if I set the fan to the highest setting still no air blows out of them. Second, the AC/Heater control unit is pretty much stuck on the setting that is supposed to only blow air out of the feet vents. I can force the switch to the other settings but it will just move back to the one for the feet. Even though the unit is set on this setting air always blows out of the defrosters and the driver vents. What are a few possible problems that I could be having with my car? And what solutions may you suggest me to seek out?

SOURCE: no air flow to dash vents and feet vents

99% of the time when they do that it is the control head. that is the thing you adjust all your temp settings on. have to purchase from dealer. have last eight digits of vin # when ordering.

SOURCE: The Air flows through only the defrost and feet vents

Inside the ventilation system there is gates that open and close to direct the air flow. These are operated on vacuum on most vehicles. The hose for that perticular gate may have disconnected somehow or has a hole in it. I suggest you take the heater controls out and see if there is a plug with a series of colored hoses on it. it so you'll have to trace each of them to see which one is the problem. Now you may be able to get some help from you local dealers mechanic who just may know the color code for that gate. (which would be a bonus) Good Luck

SOURCE: Jeep AC blows cold air at defrost and feet but not through vents

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

SOURCE: 1997 jeep wrangler ac will not blow out of main

Maybe your dashboard vents are clogged, obstructed or stuck in close position somehow.

If not, check the air hoses that carry the cooled air to the main vents are not clogged, bent, ripped or simply detached.
If its practical for you, check if they are correctly placed, clean and general conditions are ok if you can.

If above are not the issue, go to check outlets of the A/C unit, its filters for the possible reason.

2001 Mazda Protege' A/C button must have a short. When the fan knob is turned past 1, the A/C button turns off the A/C, no light, no cool air. The fan still blows, but the air only stays cool when the fan...


It's not the AC button but the fan switch. Had mine replaced with the same issue and it fixed the problem. It's beginning to fail again less than 2 years later though.

How to remove the stereo from a 2000 Mazda Protege


gently pull of the moulding around the top ac vents and control knobs, then yes, use a flat head screw driver to pry at the feathered mount at the bottom of the stereo. careful not to pull to hard the ac/heat controls could disconect. pain in the *** to put back.
