2003 SILVERADO HD AC Isuues: the truck has 155K miles AC stopped working, compressor not coming on. Only 25MV at compressor. Both high and low pressure gauge at 32 psi with AC on no change in either gauge with engine running. Before compressor stopped working the autozone fill can with a gauge red OK range when the compressor cycled on. Any ideas, should I add more R34 to bring low side up to 65 psi low side?

- 2 speed transfer case optional now?
  
  By Chuck FB · Posted 4 minutes ago
  
  Yes, the key seems to be with the half tons that if it has the Z71, then it definitely has the two speed. What got me was that the two speed AND the lower geared towing package option could not be chosen together the last few years unless it was mated up to the 6.2. Want the 3.0 duramax and 3.73 tow gears ... nope, can't get the two speed transfer case ( neighbor son realized that after he had bought his used 3.0 half ton .. where the frick is the low range ? ! ). I am still unsure which truck series, the half ton or the HD truck that the original poster is referring to for sure other than yes his question is in the HD section of this forum but that doesn't guarantee the question got asked in the right section.

  read your owners manual. there's only a few specific modes where recirculation can be turned on, and it automatically switches to fresh air if you change to the hvac to a mode that doesn't support it.

  Sunroof on Dizzy was like that. Fix it, break, fix it again, break.. Fix it again RTV it shut. Plastic gears. Love yards like that and they are few these days. Going to the mall before there were malls.

  My last three 1/2 ton GMC SLE's had the Z71 package. All of them had the 2 speed transfer case and Auto 4WD. My AT4HD has all of the above standard. In order of use, I use Auto 4WD the most then 4High. I rarely use 4LOW but like having it anyways. My next truck will probably be another AT4HD.
