RDL EZ-SX4 Stereo Audio Input Switcher

okay here we have a 2008 toyota highlander case it's not cold the customer bought it about six months ago and the AC was a little bit cold but now it doesn't work at all so what am i assuming lost the refrigerant first let's hook up the gauge now there's low sign high side we're gonna low side first we get the low side the one that says L obviously L it's down they're not the greatest place to access but I've seen worse I'll have to adjust this so it goes up now at least I can get it in the hall trying to snap it on you got a wig out and snap it on and in this case there's not much wiggling around there yeah I'm gonna turn the handle that opens the valve up it's got 65 pounds pressure it should do something so let's turn it on start it up put it on a see full blast there we go for the last let's look at it we shot the AC off and as you can see now but the pressure isn't spinning anymore
