Air conditioners in some cars are computer driven, and like hell, they can turn against you and you won't have any cold air. So, this moment, I'm going to show you how to bypass your air conditioning computer system with the simple a little $30 thermostat switch. Your air-conditioning clutch is turned on by an electric switch and if the computer isn't working right it won't turn it on. So here is how you can bypass all the computers. Unplug the switch, then get some wire and run wire from the switch inside the vehicle. There's a million holes in your car to go through, where this cable goes through, there is a rubber outlet. Just put it through with the screwdriver, then run the wire inside, and after you pull the wire through, connect one end to a toggle switch, which you can mount anywhere that you want, just drill a little hole and bolt it in. Then you get your thermostat and connect the wire to the in, right here. Now comes the hard part. This measures the temperature of your evaporator. On the Ford, the evaporator is right here, in this plastic case. You drill a tiny little hole. Now be careful, when you drilling a hole because you don't want to make a hole in the evaporator. You'll need to drill about that deep, just find a nice spot in a plastic tubing in. Then you get to the end of the tube and push it in the hole until it rubs against the evaporator and it's touching it, so it measures the temperature. Then run a wire to the out, to your battery.
Now, when you connect it to the positive terminal of your battery, make sure you use a fuse assembly to make the whole thing safe. This is a 10 Amp fuse, which is good for the AC-clutch. Now if your AC and computer goes bad, you want to fix it the way it was designed, sometimes you have to spend $700 or $800; this little thermostat, it only costs $30. Now this particular thermostat was designed for a Mazda, but they all work the same way. They measure the temperature in the evaporator, and you can set them colder or warmer by turning these little screws. Now, they may not have them in the stock but they can order for you in any good auto parts store. They're not that expensive and as you can see, they are very simple to put in. That's the way cars used to be when things are simpler and cost less to fix. So, if your car's air-conditioning computer hasn't been working right lately, -- I know everything hasn't been quite right with me but I can assure you now very confidently that it's going to be alright again.
Forget Space Age Technology buy yourself one of these $30 thermostats. This is Scotty Kilmer helping you, crank it up. And as always if you have any kind of questions just go scottykilmer.com and I will answer them.
