any new developments on this?
is it ok to just check the low side pressure with one of those cheak $20 gauges?
my a/c is not blowing cold at low speeds, but at higher speeds it will. i have an electric fan, and even when switched on high, id doesn't really blow cold. it will blow cold when first started usually, and if the temp is below 80 degrees F.
i was thinking of getting one of those cheap gauges that let you check the low side pressure, and add refigerant. are those reliable?
the truck is an 03 Lightning.
