Yes, a faulty ignition switch can prevent your air conditioning (AC) from working. The ignition switch controls the electrical systems in your vehicle, including the AC system. If the switch is malfunctioning, it may not provide power to the AC components, leading to a failure in operation. However, if the AC itself has other issues, such as a refrigerant leak or compressor failure, the ignition switch would not be the cause.
Could be low on freon,
check your ignition switch
You switch the carborator with the ac and then rewire the inside to the dashboard
ignition switch or key and tumbler.
It is not the blower motor,it is the speed switch on the dash.This is a common problem in many vehicles.
ignition switch happened on my 94 also that fixed the problem but you have to drop the steering wheel
Your AC switch may not be working properly due to a faulty connection, a malfunctioning switch, or an issue with the electrical system. It is recommended to have a professional inspect and repair the switch to ensure proper functioning of your air conditioning system.
The ignition switch is bad. Replace it.
you have an AC leak
The blower motor speed switch is burned out or the fuse is blown.
does the ac just stop or does the defrost also come on out of the blue?
Quite a number of problems can cause your AC to fail, but perhaps the most common is low refrigerant. Refrigerant usually leaks, or more accuately seeps, out of the AC system. Over time, you'll need to add more refrigerant. The system detects low levels of refrigerant and shuts off the compressor until you add more.That is NOT the only reason AC systems "stop working".Faulty compressor, clutch, relay, switch, fuse... all of these and more can fail, causing the AC to stop working.
