Hi,

I recently evacuated/vacuumed the ac system in 2006 mazda 3 2.0. I attached the can of freon to the vacuum line and opened the low side valve on the gauges. Started the car but compressor wont run. Specificly, how can I "jump" the ac compressor?

Thanks

 

you have to find the low pressure switch and pull it off, you can use a small wire to use as a jumper. stick it in both sides of the plug and the compressor will start running.
