So i just got done converting to R134, The right way, and now im having an issue with the compressor clutch not kicking in when i hit the snowflake button, although something happens, because i hear the revs go up a little in the engine bay when i hit the button. Oh and the snowflake doesnt light up blue no matter how the flaps are positioned etc. I did some troubleshooting and the clutch kicks in when i jump the plug for the pressure switch. When the switch is jumped the a/c blows pretty cold, today it is 95ish degrees out and i was sufficiently cooled in the car, could be a little colder though. Here is what all i did in the conversion.
Replaced condenser with parallel flow one
replaced all o rings
New 4 season evaporator
New Expansion r134 expansion valve
New style drier for single hi/lo switch
New hi/lo switch (This One)
Spliced pressure switch harness with terminal and wire set i got from the dealership, to accept new terminal style for new pressure switch.
The system had already been converted a bit by PO so i didnt need to add pag oil.
After i put it all together i added 12 oz of r134, then a few ounces of a stop leak concoction(which worked amazingly btw) and then added about 3-5 more ounces of refridgerent until the guage manifold read around 48psi, which is in the full zone. Idk if this makes a difference, but when the car is turned off and the gauges are hooked up, the pressure on the low side skyrockets all the way to the top.
I remember seeing somewhere that it should take about 25-28oz of r134.
Any help on why it wont run unless i jump the safety switch would be appreciated
