You either have a bad switch or you need to check your fuse or relay for your a/c. To check your switch: you need a multimeter or voltmeter. You'll need to get to the back of your switch, keep it plugged in and find your power wire to the switch. Then put the positive end of the voltmeter in the back of the connector into the power(don't push to hard or you'll damage the connector). Then put the negative end of the voltmeter on a good ground on your frame or something that touches your frame. You should get a voltage reading of 12 volts. If there's no voltage than somethings wrong with the wiring up to your switch. If there is voltage, than you need a new switch.
You may need to charge your a/c with refrigerant.
could be a bad fuse or ac relay,also if out off coolant ac clutch will not work,
The first knob controls the fan speed. The second selects the temperature. The third selects which vent it will come out of. And the last will select recirculated or outside air. Turning them all to the left will give you max AC.
the control is electrical i do believe so you would need to replace the switch. the switch is behind the knob you turn. of course you will need to remove some parts to get to it.
That is normal.
does the ac just stop or does the defrost also come on out of the blue?
The AC takes the moisture out of the cabin air and that helps clear the inside of the windshield from moisture faster.
Turn the defroster on. If you have a separate AC switch, turn it on also. The AC should come on with the defroster automatically, but might not. If no AC, set the vent control to outside air instead of recirculate.
as soon as the ac is turn on the cooling fan should come on if not there is a problem with that take it to a ac shop thay can find it fast ..
Yes, there is a control knob on the gen-set that will have a label called field excitation or just field. Look at the volt meter and turn this control in a clockwise direction. The voltage should increase as you turn the control.
Most common problem LOW FREON
The ac pump may be seized up.
Yes, the windshield defroster will turn the A/C compressor on.
It could be a bad fuse, compressor, or condenser. To diagnose the problem if it is not a bad fuse will require a trip to the shop. How about at any other fan speeds?
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
generely it won't come on if the level of freon in the system is to low, it might have a leak or may need a recharge
no ofcourse not water would just dry off even if it does not or does come from the AC
Try pulling on the knob. Usually these are press fitted on, and will pull off with a little effort.
Yes that is fine. If you are worried about the bills the best thing to do is to turn the ac down not off when you leave and then when you come back, turn it back up to your comfort level. This way you do not have to try to re-cool the whole house.
turn on the ac and open the door or window
Depending on the year. My 98 Exp EB has the knob on the dash to change the temp in the front and the console on the roof has another knob to change temps in the back
SCR's are mainly used in AC circuits. They could be used in DC circuits but they then would not be able to turn off. They require the zero crossing of the AC circuit to turn off. Then when positively biased they can be turned back on.
bad motor or capacitor
