Window ac blows when drop to 72deg why - Frigidaire 15,100 BTU Heavy Duty Window Air Conditioner

It is likely to go again because you haven't found out 'why' and corrected it. Fuses blow when there a dead short to ground or something is causing more resistance than the fuse can handle.

as for drivers window my money says its the switch. your local wrecking yard should be able to get one for you

If you gassed the ac system your self then it mat be overfull and that is why it is not working and if you did no check for leaks (why else would need gas) then it may be all pumped out . The AC compressor takes a lot of power to drive and all cars loose around 300rpm's when it cuts in so if you have an idle too low then it will drop below needed idle rpm's . Most cars have a compensating unit the raises the idle rpm when the ac is working so check out your system for a faulty unit there.

i bleave you have a bad pluge out lit or a bad breaker but the wiring from the window unit to the breaker may not be tight

This is to give you more power when needed,it was designed to do this.

lets just say a modern unit would run about 15mins every 2 hours.(if the doors are kept SHUT.(they dont count how many times the little darlings leave the door open)

First of all, an extension cord and GFI receptacle to run an AC unit will almost always blow either GFI or circuit breaker or both due to large current draw from AC unit. If an extension cord needs to be used, keep it as short as possible, and use the heavier gauge that is approved for AC use. What happens when you use an extension cord, is the voltage drop that will happen by the time the AC gets power. With any voltage drop, the amperage draw increases, so a 15 amp circuit breaker will most likely trip. Nowadays, all AC units are wired with a minimum 12 gauge wire rated for 20 amps.
You say nothing is happening now, is that to say that the fan only mode doesn't work on the AC unit either?

check main vent on off switch.

AC units do take the humidity out of the air and water collects in the bottom. The unit should be tilted slightly downward on the outside so that the water runs outrside. Make sure the drain holes are clear. The pinging noise is common, the fan is hitting drops of water, nothing to be concerned about

There's a rod assembly that opens and closes the vents in the car for the automatic climate control. It's supposed to open all vents to the AC feed when in AC mode. BUT, if it slips loose, the default status is to feed heat through (you can open a window in the summer, but you don't want AC blowing in your face and on your windshield in the winter). In my case, the driver's side was working right, pumping cold air, but the passenger side was actually dumping hot air into the car. Friend who fixed it for me told me he just had to drop the glove box etc. on the passenger side to get to the rod and slipped it back into place. I'm not agile enough, but if you are, you can probably crawl around under there and figure it out - or get a friendly mechanically inclined young friend to do it for you. Probably in the mechanic's manual for the Caddy (I don't have one).

Think this will fix it for you - did for me.
