Legally you can't without the EPA's Secton 609 certifacation, because any refrigerant in the system must be removed by a licensed technician. And even if its empty of refrigerant, after you relace the compressor you must pull a vacuum on the system to remove air and moisture. I would recomend taking it to a garage.
The guy above probably owns an AC garage. You need to have a certified mechanic "discharge" and "re-charge" the refrigerant. However, the act of replacing the AC compressor can be done by you (although this depends on "you"). My local shop charges $85 to remove the refrigerant and replace it again after I have changed out the compressor. Tomorrow I will take the old compressor off and put the new one in...from what I gather so far...this entails removing the plastic cover below the compressor, remove the belt, remove the compressor, replace the new one and use a wrench on the belt "auto-tensioner" to get the belt back on. Run the car and make sure it works properly...then take it back to the garage, get the refrigerant re-charged and you should be good to go!

Because its not really a Mazda 626... Its a Delorian... ..
Should be R-134
if the distributor is not firing. check to see if your engines compression; if compression is at zero, then you need a new engine. Mazda millenia, 626, ford probe have this problem.
the thermostat on a Mazda 626 is vey difficult to find i replaced it myself and i found out it was right under the air filter box.

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.

torque converter clutch solenoid circuit
98-99 Mazda 626 do not have speed sensor. Speed data is obtained from ABS. Therefore if you are having speedometer issue then the problem is more complex as you have expected. Good luck!
