Don't be a fool like me and neglect knowing that you are running on one or none condensor fans when you turn on your A/C. Its so simple to make sure these fans are running and that your A/C system will perform.
I started noticeing my A/C compressor making more noise than usual.
Then I noticed that the compressor was barely running when required.
My first thoughts was that I was running low on R12 from a leak somewhere.
I checked the site glass at the front of the hood area and had bubbles appear as the system turned off and on. Good reason to think R12 was low.
Stopped using the system and talk to my great neighbor Richard who is a Refir Tech. I you don't have a great neighbor, go out and get one.
We set up all his gear and bleed in a few ounces of R12. Nothing changed.
Richard took his time and looked and listened.
He noticed that the Triple Pressure Switch was clicking on and off in unison with the compressor kicking in and out. So why is the pressure switch kicking off the compressor?
So he says to me, where is your condensor, so I showed him the two in the front. He felt in the wheel well and said, well aren't there fans and why aren't they running. I scrambled to open the manual and we found we should check the two 10 amp fuses shown below in the picture. Both where blown. Who knows how long I was driving with just one fan working. Without these fans working, the heat from the freon was not rejected, pressure built up, the compressor has to work harder (hence the noiser compressor) and on and on til I would have gotten a big bill!!! There is another fuse to check and if those are good and one of your fans isn't working, then there are the relays to look over. You can hear those condensor fans when they are on quite easily, just turn on the A/C and get down by each Condensor and listen. Also you can feel the air flowing out into the wheel well, just in front of the front tyres.
Just a note on those fans, they should come on when the compressor kicks in and turn off when the compressor kicks off. Sections of interest in the manual would be 22-3,22-52/3/4,22-73 or the whole section.
