Anyone know what year the US manufacturers switched from Freon to R-134? For OEM factory installed truck air conditioners.

 

Or was it gradual over a few years?

I had a '95 GM vehicle that still had R-12. So not sure if it was some models or what. When the compressor went out I had it changed over to 134. It leaked for a while but I had a big stash of R-12 cans that I "aquired" a long time ago for a whopping 0.49 each as the price tag on it says.

OK,Let me rephrase that...GM switched over the trucks in 1994 to R134. (My '93 K1500 had R12,My '94 K1500 & '94 S10 ZR2 had R134)

I think I remember that some cars,Mainly Geo's I think,still used R12.

I know my dad's '95 Lumina has R134 in it.

I can actually chime in on this one. Where I work I had to take an A/C class to work on the machines we will be producing in '09 and Federal law says mandatory switch over for ALL Vehicle Manufacturers is 1995. I guess if yours was an early '95 it could have the old system of R-12, but all from '95 on MUST be R-134a. Just my .02 worth.

Mine was an early '95 S-10. I know it was early because I bought it around October of '94. Friend bought a '95 later that year and his had the 134. His also had DRT's and mine didn't.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
