Why do you get total loss of all electrics

Its possible, but if trim stopped first, then you lost everything else, I would doubt it's the fuse. Unless they're on separate circuits. First check your battery connections and voltage. Next check for power at your fuses. If they're good, check if you have a main power solenoid. If you do, its possible the coil has gotten weak or the contacts are worn. Hopefully this helps. Electrical issues can be a variety of things but are usually simple.

When i am vacuuming my sucks the dirt up when i am pushing it forward, but when i pull it back, the dirt comes back out on the carpet

This is due to a loss of suction. The roller brush sweeps the dirt to the hose area, but with no suction, when you pull the vacuum back, the brush just kicks the dirt back out. This is most likely due to a clog in part of the hose system.
You don't mention whether it's a canister or upright, but check all hoses and tube.
It can also be due to a full bag or clogged filter. Another cause could be a fault in the switch or wiring that turns on the power nozzle (only if it has a separate motor) but not the vacuum.
The fan blades could be broken or worn, which would allow the vacuum to run, but with no airflow/suction.
Or most costly, the motor is worn out and no longer working.

Freezer is warm, not freezing at all, fans run

If the fans your talking about are in the refrigeration section, then the unit is not in defrost. The interior fans shut off during the defrost cycle.
There is a condenser fan motor in the machine section by the compressor. If it fails, the problem you described can occur.
If that fan motor is still, and the compressor is cool to the touch, then no power is getting to the refrigeration section.
Could be a bad thermostat, or the unit has tripped off on the high pressure safety switch. The high pressure switch can be one of 2 styles. Auto reset, which means it will try to restart the compressor when the pressures become normal. The other has a lock out feature that requires it be reset manually. If it goes out on the high pressure switch, once reset, check the condenser fan motor to make sure it is running and/or excessive dirt in the condenser, which must be blown out.
Other causes can be a total loss of refrigerant, or a compressor that won't run.
Short of a broken wire all items listed except for a dirty condensor and reset of the high pressure switch, require a decent knowledge of electrical, Knowledge in the use of a VOM meter and amp-probe, as well as a set of refrigeration gauges.

Do i need a special switch to run an exhaust fan/light simultaneously?

No, you can pigtail the fan and light together with a wire nut and another piece of wire and connect that to the top of a single pole switch. Connect the Common (hot) wire to the bottom of the switch, and the light and fan will operate at the same time. Just make sure the total Amps of the lighting and the fan doesn't exceed the rating of the switch.

Be sure to disconnect the power to the circuit before making any connections and if you have a metal switch box, wrap around the switch, covering the connection screws with 2-3 complete wraps of electrical tape to prevent accidental shorting against the metal box.

If you want to have the ability to run the fan and light separately, you can get a over/under switch that will fit into the single gang box. That will let you turn on either the light or the fan, or both at once.

If you have any specific issues concerning your particular installation, please use the comment box to post more info or follow up questions and I'll get back to you.

Hope you find this Very Helpful and best regards!
