Ok on my climate controls for the blower low and the next speed does not work but the 3rd and high speed does? i replaced the switch but still no luck. and on my headlight switch ht automatic does not work and my fog lights do not work and the bulbs look fine. but i can turn my parking light and headlights on manually and they work? i have no clue where to begin? any help?

 

Sounds like the blower motor resistor and the headlamp switch to me

 

where is the blower motor resistor located at? and thank you
