If power is lost between battery and fuse block, check wiring. There may be a fusible link that has gone out. Some fuses are hot at all times, but with key in the on position, all fuses should be powered. If not on yours, you may need a wiring diagram from a repair manual to troubleshoot.

Wont be difficult at all, you can either use a wire solder or use wire connectors just strip the wire and insert wire crimp connectors but you have to match the wire that are cut to each other,

look for a serious exhaust or intake leak. look for bad wires to the o2 sensor or map sensor. just for starters.

This could possibly be a block in your heater core or the thermostat may be going bad and not circulating the antifreeze the way it should once the engine has warmed up. Have you had your antifreeze system flushed? If its a 2000 then its 10 years old and the system should be flushed and refilled

sounds like you have a bad actuator motor that is what moves the door in heater box to change from hot to cold

your heat/cool and vent selection options are controlled by engine vacuum through small clear tubes attached to the rear of your climate control interface. Other vehicles have small steel pull wires that operate the desired changes. You might try removing the trim and any fasteners affiliated with the interface/console. GENTLY pull outward and look to see if any of these tubes are pulled off or cut/damaged. Did anyone recently install a new stereo in the vehicle? If so, the vacuum tubing and or pull wires that change your outlets could have been damaged when the stereo unit was pushed into place. Hope this helps

It sounds as if you have a fuel filter either stopped up or either an injector may be stopping up.

Most parts stores carry a "piggyback" terminal that can be used with a fuse that will provide a male spade lug that can be used for such installations. I suggest you use the "AUX" fuse as it will be a heavy enough circuit.

check the wires behind the seat control on the side if the seat, sometimes the wires will get pinched and short to ground
