Hi All,

My AC blows semi cold air only when driving but isn't too cold at a standstill. I believe my truck either still has r22 or r12. Are there any DIY guides to change to 134A and any recommended kits?

Thanks!

 

Yes, quite a few out there, Google: how to convert r12 to r134a

Vehicle model doesn't matter except when buying specific parts, the conversion is what you want to watch
And watch a few different videos on it
Also look at your 1994 fittings, it may have already been converted to R134A, 1994 was the last model year R12 was allowed in new vehicles

You can still buy and use R12 if you can find it and its not stupid expensive, lol, its not illegal
Sale and use was never banned, production of R12 was banned in 1995/6, so whatever is left can be used legally
