I have '95 F150 that I use as my home depot truck and for various truck duties while daily driving a sedan. Truck currently has 253k and original compressor and condenser. My ac has not been working and I decided that I want to get it fixed. At the same time I have also been trying to track down the reason for an inoperable odometer and speedometer and a few months ago I was messing with the fuses. I find out later that my ac quit and I was like great. Add that to the list. I haven't messed with it lately and today I decided to revisit the fuses and low and behold I find a fuse on the floor board. I look up the fuses in the diagram on the truck and it's the compressor fuse. I pop it back in and the compressor roars to life. I can't believe I overlooked that and suffered in the Texas heat on the occasions I've needed to drive it. Oh well. Now. I had already had it in my head I was gonna spend some money on it. The ac in this truck works but it doesn't work that well in the hot Texas traffic. It works pretty well with significant airflow. I know the condenser is original and pretty beat up. The compressor is original too. It's not quiet but it's not too noisy either. If I take this to a shop to have them look at it can the vent temps and pressures tell the story of how well a compressor is doing ? I haven't checked the charge since it was repair about 8 years when a leak was repaired. I figure I might replace the compressor and condenser anyway or maybe just the condenser. I just don't want to replace the condenser and then the compressor crap out and then I have to replace both. I also don't want to replace a good compressor that seems to be a well built one. What do you guys think ?
