Can a scan tool make a car blow cold air?
They can plug in a scan tool and make my car blow cold air but it won’t work without the scantool, the scantool can kick on the compressor. They checked all fuses and relays. They tried replacing A/C amplifier and they tried replacing (A/C switch?).
What should I use to test my AC switch?
I’d just turn on the AC switch, and use a voltmeter or test light to trace where the 12 volts from the switch goes away. But you will need the wiring diagram. And the mechanic should be able to do this in his sleep. If they can get the AC to work with a scan tool, the heater/AC control assembly requires replacement.
Why is the AC not working on my Scion tC 2012?
Car A/C not working. Shop can’t figure it out So I have a scion tc 2012 and the A/C no longer works properly. The AC blows lukewarm air (seems to just blow whatever air is outside) when I press the AC button, it doesn’t kick on the compressor. The heat works fine.
What should I do if my AC switch wont turn on?
Joshtalks, I agree, seems to be an electrical problem. I’d just turn on the AC switch, and use a voltmeter or test light to trace where the 12 volts from the switch goes away. But you will need the wiring diagram. And the mechanic should be able to do this in his sleep.
What to do if there is no power to an A / C compressor?
Re: No power to a/c compressor, I have checked the fuses,… The trigger from the dash switch activates the relay which in turn switches on the solenoid pulley to engage the compressor to work. If this circuit is traced the fault of a open circuit can be found out. If there is no power in the fuse or relay then the main wiring must be checked.
