Ok I bought my mj last year and the A/C has never worked.
The truck sat for at least 2 years before I purchased it and I haven't driven it much since then since it has a very bad rear main seal leak and as I found out a month ago the drivers seat belt has a lovely rip in it and the po just covered the ripped area with duct and electrical tape....., but what is a jeep without some dodgy safety features?
What should be my first steps in getting the A/C working again? How do I tell if it has been converted to R134a?
I am guessing just get something like this http://www.amazon.com/RED-TEK-R12a-Refrigerant-Recharge/dp/B00DJDYORU/ref=pd_sim_sbs_auto_1?ie=UTF8&refRID=0ER018XRE5RMW1DQ77TJ to start with?
