Check first for a runnability problem eg: tuneup etc. A/C is a strain on a smaller motor (I'm assuming a 4 cylinder, older vintage as you gave no info.) and if it's not running right in the first place, turning on the A/C will make it worse.
I would check the power brake booster
It could be the ICM or the pickup module.
If it's the one on the radiator, and it stops running after a few minutes, then it's been designed by Mazda to work like that. If it runs until the battery goes flat, you have a short circuit somewhere, supplying the fan with power.
Have vehicle scanned to determine the problem
what is your ?, a MAF is basicly a IAT The Mazda Protege and Protege 5 2.0L engine has an IAT Sensor located just past the factory air filter box. It is a two wire sensor that plugs into the intake tube via a rubber grommet. The three wire plug in the Mass Air Flow Sensor. DO NOT Unplug either of these sensors while the vehicle is running or key turned to accessory. Will cause a flag in the computer and turn on the Check Engine Light. Hope this helps.
what causes aknocking sound on mazda T35 engine when its running
The engine will stop running. This is not an interference engine so there will be no engine damage. Just replace the belt.

I would check the power brake booster
To keep an engine running well, a person must use the appropriate fluid type in their car. A 1999 Mazda 626 takes 10W30 engine oil.
Check the engine thermostat.
gears are seized when the car engine is running but when off they can be put easily

The Mazda Rx7 has the Wankel Rotary Engine in it

Replace the Mazda engine.
