my air conditioning/heater only works consistently on 5, which is the highest output. Sometimes it will work on lower settings and other times it won't work at all, same with my daytime running lights the low coolant light and service engine lights also go on and off at will.

Replace blower motor resistor to fix blower fan.

Have car computer scanned for error codes for other problems.
