93 Bronco
My 93 Bronco blew the rear end last July and sat till march when I got gears put in front and Back. When I cranked the AC up it didn't cool at all and the compressor never kicked on. I hooked my gauges up and added a can and a half of 134 to they marked about 40 low side and 220 high side and the compressor stayed on continuous. I have low air flow at the vent so i assume the resistor is bad or dirty but my real concern is that the receiver/Drier doesn't get cold like it should and the air at the vent is only mildly cold at highway speed (about 65f) and mildly cool parked at 2000 rpm (75f). Because it was so low, I think the leak may be substantial causing moisture to enter the system and cause ineffective cooling so my next step is to try to find the leak, repair it, replace the receiver/dryer, vac the system out and recharge. Does anyone have any ideas or recommendations? A mechanic friend told me he thinks I have a weak compressor does anyone know what the symptoms for a weak compressor are?

After reading through many articles and forum posts I found out there are different condensors for R12 and 134. My 93 came stock with R12 and I converted it years ago but it never cooled very well like my 98 expi. I'm curious if the condenser could be changed to a 134 condensor and if it would be more effective. Has anyone hard of this or have any experience to share.

If the fan is running and you have poor airflow, it's very likely that the evaporator is plugged with dirt and debris. You will need to open the evaporator case to clean it. Every bit of unfiltered air drawn through that system since 1993 has flowed through the evaporator and those tightly spaced fins make a dandy filter. Rodents also seem to love nesting in the evaporator case on parked vehicles.

Thanks for the info. I thought about debris in the evaporator and plan to open it up to clean it out a well as the fan wheel.
As for the condenser, please forgive my ignorance but can you explain alittle about the difference between parallel flew condenser and the R12 condenser? I'm not real familiar with it want to know if you can tell them apart just by looking.
