I have an '86 GMC Jimmy Runs great (It should, It's got lots of new parts!) but A/C is a problem. Operates/blows cold air for 20~30 minutes then A/C Fuse blows. Compressor, drier, and orifice have been replaced with new GM parts, new PAG oil and R134 refig by professional. Truck was converted to R134 refrig some years ago when a rebuilt compressor was installed. Any thoughts? TIA, Speced.
