Did anyone save my info on resetting the warning lights for the A/C system?

I know I posted it last winter or spring, but cannot find it. My A/C started putting out lukewarm air a couple weeks ago and I checked the indicator lights and it shows it is low on freon. I now know that you cannot just keep adding and the light will go off. There is a series of key operations that need to be done to reset the lights. I think it's 8 but that seems a lot. Your assist will be appreciated.

is this what you're looking for?

 

The A/C system is recharged and the green light is flashing slowly as it's supposed to. I was just getting ready to add my 4th 12 oz can of freon when I read the TINY PRINT at the bottom of the system status that informed me a reset of the fault had to be done once a fault had been fixed. You have to turn the ignition key off 1 second, back of for a second and repeat that three more times for a total of 4. Then the monitor will reset. I decided to check that out and sure enough the light was green. I have to admit I should have either followed RandyA's advice or taken the truck to an A/C place to have the recharge done.

Unless you know what you are doing you could damage the system beyond repair by just adding refrigerant without knowing what your operating presures are.

 

I have seen a kit in some of the box stores that sell the cans of refgt. This kit contains a hose with adapter but most importantly is that there is a guage on the hose that shows several ranges from yellow through green to red. This is a good rule of thumb guide and worth the investment. If the operating pressure is in the green section you are most likely ok with the refgt level.
