Detailed Product Overview

This HVAC blower control switch is used to select blower motor speeds from the climate control panel. It is listed for many Dodge Ram, B-Series van, Ramcharger, Caravan, and Chrysler passenger-car applications, including 1994-1997 Dodge Ram 1500, 1995-1997 Dodge B1500, and 1974-1984 Chrysler New Yorker. If you are replacing a worn blower selector on a Dodge Ram 2500 or Chrysler Newport, this part number 37636 is the type of electrical switch commonly used to restore normal HVAC fan control.

This part cross-references 1S1959 and SW212 for the same application.

What It Helps Fix

• Blower fan speeds that do not respond correctly
• Intermittent HVAC fan operation at the dash switch
• Worn or burned selector switch contacts
• Loss of one or more blower speed settings
• Electrical connection issues at the HVAC control panel

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle application before installation. This switch is listed for front HVAC locations on many vans and B-series models, while other applications are noted without a position designation. Compare the original switch to Four Seasons 37636 to confirm the male square connector and 4-terminal layout match your vehicle.

For best results, inspect the blower motor resistor, wiring connector, and related HVAC controls during replacement. A damaged resistor or heat-affected connector can cause symptoms that resemble switch failure.
