What type of freon did the A/C in a 91 Nissan pickup use? I have some new "old" cans of R12 and was wondering is was comtabile... The A/C unit has never been converted.

134a is what they use these days the old r12 is obsolete and not compatible.

they sell the new stuff at walmart or kmart in a do it yourself kit.
