Need to add freon to ac compressor
SOURCE: a/c warm low and high side pressures wrong
it could be one of 2 things.
you didn't vaccum it all the way or there is b clog in the system. next time u flush it run about 1/8 cup of rubbing alcohol through it . then push clean air through it. then refill it. if that doesnt work replace the seals on the compressorlow and high side lines/manifold.
SOURCE: ac low side service port location
Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry
SOURCE: Where is the low pressure line AC for Express 1500
Look for the accumulator(silver can a/c lines go to) on the passenger side of engine area. The Low side charging port cap should be on the side of the accumulator.
SOURCE: Looking for low pressure port for servicing Freon
The ports on my 2005 silverado are on the same line,which is very confusing but, in between the two ports is the metering device (orifice) which changes the high pressure gas into a low pressure gas.The two ports are of a different size,with the low pressure being the smaller of the two. You can put your hand on the line, on each side of the metering device connection and the high side will be hot and the low side will be cold
