Go to an autoparts store..perhaps Walmart would have it but... purchase a do it yourself pressure valve gauge to assist you. Just follow the directions on the can of freon it usually comes with and you can't go wrong. The gauge is interchangable with extra cans of freon if you need more than one can.
It would be better if you bought a 134a refill kit which has a gauge. This is important because you would be avoiding overfilling the system and damaging the compressor/ other componets. There likely is already some gas in your system, and in the long run you'd probably save yourself some money. The "bicycle type" gauges work, but only as a very rough estimate- a gauge is the best.
To the right of your headlight switch is a dimmer switch for your gauge cluster lighting - I'm not sure if it's the same on your F150 as my Explorer but when my dimmer switch is rotated all the way up it turns on my interior lights . Also if you have a door ajar light lit up in your gauge cluster , you probably have a sticking door ajar switch
