Benzmac, what do you mean by update the fuse? is this a simple 20 amp vs 15 amp in the fuse box under the hood?
i replaced /updated high pressure fan switch on reciever dryer. also turned out i had the wheels on the manifold gage turned on instead of off (it pays to re-read instructions!). now i am getting more reasonable measures of 30 psi low side and 225 psi high side, it is still not cool enough though, should i add more 134a to get measures around a 45psi low and 325 psi high? what should temp be with a thermometer stuck in the vent inside the car 45 degrees?
