What kind of cold is normal for normally operating AC unit?
I looooove coldness, I sleep better in the cold.
Summer is coming, I want an ice cold AC unit.
Should a 98 Blazer need a recharge?
I know my compressor is working, I see the end of it spinning.
Installed new belt. Probably drain and fill rad fluid.
Its what, 17 yrs old, wowsers thats old.
Recharge?
Is there a better gas to fill with in 2015, something that will give me ice cold air. Or is it the same gas we use now as 17 yrs ago.
I did a little searching myself, Found out there is no in cabin air filter.
Might need to buy or better yet rent a $40 ac guage unit see what kind of pressures I am dealing with on high and low sides.
Right now the thing is blowing cool air, but its not cold like my momma's 2005 Acura MDX.

GM switched to R134a refrigerant in 1993 when R12 was outlawed. R134a is soon to be outlawed and replaced with a new chemical. Rule of thumb with a CCOT, (clutch cycling orifice tube) R134a system, is roughly a 20F degree drop below ambient temperature. If you get more than that, consider yourself fortunate. There is a "tweak" that can be done to improve cooling that involves replacing the fixed orifice tube, (FOT) with a variable orifice valve, (VOV).
Checking high and low side pressures is not accurate for determining the state of charge on a CCOT system. The ONLY way to know for certain, is to drain, evacuate, and recharge the system with the correct amount of refrigerant.

Yeah the "experts" on youtube say there is loss of refridgerant. Makes sense.
Thanks for the info Captain Hook
I am going to look into the VOV.
As a sidenote and a bit of a rant because I am bored today and got some time.
I personally like to cruise in the summer with all my windows up, ac cranked and the sunroof cracked to get good circulation within vehicle. The other reason is so the tunes can get outside the vehicle and tell others how cool I really am, without the obvious new car (which most likely has AC) and they have all the windows rolled down. Which is a total sign of a "poser". Hopefully the Flamers will win and kick Vancouver out and the "Red Mile" will go crazy.
