Get a mechanic to have a look ,water level low hence the heater is cold and ac taking a long time to cool because the fan isnt starting up when ac is turned on ,Sounds like your fan is playing up and you may have cooked the head gasket??

Car gets hot when Idle

You might check your cooling fan at the radiator; it may not be running. If it's not, track it down (fuse or thermal switch) and fix it!

99 chevy blazer blows heat only sometimes

You need to check for a loose ground again. The dash seems to have a loose ground. Your heat and ac are controlled by motors that get input from your switch. You might try following that harness and see if there is a loose ground. Other than that I don't have a clue. You might also check near the firewall and make sure the ground strap there was bolted to the engine.

Start by flushing your coolant system and replacing your thermostat. You may later find that you have a clogged heater core.

Cold starting problem

this is caused by the fuel pump pressure check valve, when this valve fails the gas drains out of the lines and filter and back to the fuel tank, then when u start the pump has to pump the fuel through the lines and filter and then the air has to be purged out of the system by the injectors, this all takes time, result long crank times and numerous start stall. The pressure check valve is part of the fuel pump, the pump is in the fuel tank.
