Four Seasons 37643 switch for the 2004-2007 Chevrolet Aveo and other vehicles is a rotary selector that controls the HVAC blower.

  • Engineered and tested for years of trouble-free operation, backed by over 50 years of mobile A/C experience
  • Rated to carry up to 20 amps
  • Contacts ensure proper conductivity
  • Vehicle-specific application
  • Zinc coated to resist corrosion

If the blower works on only some settings or cuts out as you turn the selector, that can mean this switch is worn. The blower motor or the blower resistor may be behind it, so rule those two out first.

It also fits the 2006-2007 Chevrolet AVEO5.
