Have Ford Questions? Ask a Mechanic for Answers ASAP
Greetings! If your air conditioning in not working, or working but not up to par, there can be a few different things that can cause this. There can be anything from restrictions in the system to your blend air door vents not working properly. If all of your freon has leaked out or even if the freon level is a bit low, the computer will not even turn on the compressor. This is to prevent damage to the compressor and the components. This is very common! If the compressor is cycling on and off, than the system is just slightly low on freon. This will cause the AC to work, but poorly. Look for moisture around the outside of the AC fittings. This will indicate a leak. If no moisture is detected, you might just be able to get away with recharge.
I tried to add freon but compressor would not engage so I bypassed the low pressure switch but still the clutch did not engage on the compressor I checked the plug and I did not have any power
Well you could have a blown fuse.
Have we checked the fuse for the compressor?
Ok... so if the fuse is good to the compressor and the compressor does not have power, it looks like we have an electrical issue going on with your vehicle.
WHat type of focus is it? Is it s Zx3, zx5? Single or dual overhead cam?
NO, the compressor should engage.
Let me pull a wiring diagram...just a minute.
Ok... the computer grounds the relay so that it will power up the AC compressor.
If you do not have power at the compressor, chances are that the computer is not grounding the AC relay.
I would be willing to bet its because the freon amount in the system is not correct. How much freon did you put it? Did you evacuate the system first?
Here is your wiring diagram.
You got it!
WOW! THats impressive! I am serious!
Most people do not know that much!
YES! One is a power and one is a ground. SO in theory if you have no power, all you have to do is add power to the compressor (and it should have ground all the time) the compressor should kick in.
THanks for the accept!
Get your AC system evacuated and recharged and I think you will be good to go!
