MY AC WORKS FINE ON ALL 3 SETTINGS BUT THE 4TH WITCH IS THE LAST SETTING DOES NOT WORK AT ALL Y?
Does it do the same if you put it on heat it could be the resistor
SOURCE: blower motor & resistor on
just change the resistor b/c when resistor go bad they get stuck on high or low. selecting on low give you more resistor and less flow of air from the blower and on high side you get less resistor and more flow
good luck

My bet is that there's a relay at fault... but first: have you checked the fuses? the high blower speed draws a lot of power, so sometimes it's fused separately from the other speeds. This means that your fuse for the slow blower speeds could be blown. Also, because theblower draws so much power, you'd need a HUGE switch to switch it directly, so they use a low-power switch inside the car, and a relay (usually under the hood, but sometimes under a seat (check your owner's manual) to do the heavy work. These are often split the same way, with the high blower on one, and the slow on the other. These are the things that are easier to check, but it could just be that the switch is bad. Mid 90s Land rovers and Range Rovers have the same problem, where the only blower speed that works is HIGH, making the cabin sound like a wind tunnel... Just the switch. The switch can be a pain to replace if you do it yourself, but do check the fuses first, and see if you can find the relays. if the fuses are okay, and you find the relays, try to find the one that's for the fan and swap it out, it shouldn't be more than 3-4 dollars from an auto parts store, just bring in the old one to match it, or swap it for another relay that's nearby and has the same pins. If the swap works, just remember to get another relay, because the one you "borrow" from another circuit could be the door locks or the headlights or something else important....
SOURCE: I need the firing order for the 1992 mazda protege
Firing order 1-3-4-2
Cylinder number from passenger side to drivers side 1-2-3-4
The rotor rotates towards the left (anti clockwise) #1 post is towards the passenger side headlight to the right is #3 next right is #4 nest right is #2 next right is back to #1
Good luck and hope this helps.

Freon in ac system is probably low. Might even have leaked all out. The right way is to check it with a set of gauges. Most autoshops can check that and go from there.Other than that check the fuses.
SOURCE: where is the blower motor resistor on a 2002 mazda protege?
just remove the glove box and its right behind it just take the white pug out and the two phillips screws to remove the resistor out, replace with the new one and cool off!!!! Hope this helps
