Air conditioner compressor
My 99 Expedition air conditioner compressor has just started to cycle on and off about every 5 seconds and I'm not getting any cold air from the vents. I have never had the system recharged. Think the constant on/off cycling is a result of low refrigerant? I guess there could be a leak but it has works great the last 11 years.
Thanks

Can I put the freon in myself? I have a haynes manual I can check out but is this something pretty straight forward?

You should first read the FAQs, but yes it is pretty easy to do. Pick up 2 cans of 134 freon and a DIY tool that has a gage at the parts store, then read the instructions that comes with the installation tool. It is pretty easy but if there is a problem in the system you may still have problems afterward, there is no substitute for a qualified tech.'s evaluation. I have been fortunate in only having a very slow loss of freon and have only had to add 2 cans after 9 years and that was a little over 2 years ago. Todays cars and trucks are very reliable if basic maint. is done on a regular basis.

I had two Ford products which exhibited the same symptons as your air conditioning system and each one cost me $1100 in repairs. Since then, I had another Taurus and a Volvo with the same problem. On these two vehicles, I got by with adding one or two cans of freon every 3-4 weeks during the summer season for the last 3 years. The leaks do not appear to be getting worse. I will continue doing this as I live in New England and we have a short summer season. The kid in the autoparts store was telling me that he needs to add a can of freon every 12 days in the summer. Again, he can buy a lot of freon before the $ 1100 repair makes sense.

The A/C compressor is run in the winter too when the defrosters are on. This has the benefit of drying out the air and preventing the windows from fogging up.

I added 2 cans of freon this weekend and it seems to have corrected the problem. My repair manual said to look for oily type deposits near the connectors as signs of a leak. I think I probably do have one on one of the connections. I'll just have to see how fast the leak is. Thanks for the responses.

Nearly all of the a/c connections show signs of seepage after a year or so of use. The easiest way to pinpoint the offending connector is to use the Dye check method, you will know for certain in 1 day.
