Have 1997 buick lasabre need to know if there would be power running to compresser i freon level was low
thanks how would you get the freon to go in if the commpresser doesnt come on due to low freon also have the rightfreon thanks
When new parts have been installed, the lines will be full of air, which must be removed using a vacuum pump. Then connect a supply of refrigerant and allow it to flow into the vacuum with the engine off. It will do that just because of the pressure difference-- it works best to turn the tank of new refrigerant upside down and charge as liquid (which is safe as long as the engine is off). That will build enough pressure in the system to close the switch and then the compressor can be started to complete the charge.
Thanks I see what your saying but if you dont have vacume pump can this still work by butting refrigerant in upside down without vacuming it or do you have to vacume it
The air must be pulled out of the system with a vacuum pump before filling with refrigerant for the AC to work decently.
thank you very much ill have a shop do that or can you rent the vacume part from a auto parts store
Often you can rent vacuum pumps. You will also need a real gauge manifold and a can tapper. After spending all that money on new parts, it makes sense to get rid of the cheesy hose with the color coded dial gauge and use real pro tools.
ha true thank goodness for warrenties without naming because the compresser that was on was ffairly new parts store replaced everything free only had to buy condenser but defently looking to buy the right tools
