Temperature gauge drops to zero after a while of driving and the air conditioner stops working

1995 Ford ranger 2.3
Code at part sore came back (p1445) purge flow sensor circuit high input
(P0118) engine coolant temperature sensor high circuit...
Dome light fuse sparkle and blows immediately upon insert
Driver side DIM headlight blows. Continuously keeps cranking, have to pop clutch to get it to stop
Fuel gauge and temp gauge needle dead, except when truck is turned off fuel gauge will go just above E.
Speedometer is off about 8 mph
Windshield wipers when on wil go fast 3 times and stop momentarily then work correctly on low for a moment then fast 4 or 5 times pause then work correctly.
When slow down for stop, the idle is very high upon complete stop the idle will go down.

Engine running hot seeing steam rising from hood. I see no coolant leak and temperature gauge stays in middle of Cold-Hot.
