Ram 3500 HVAC Pressure Switch

The HVAC Pressure Switch on the Ram 3500 serves to protect climate components from damage. If the refrigerant pressure falls or exceeds a certain level, the truck's HVAC Pressure Switch stops the compressor from functioning. This small HVAC Pressure Switch is in-line and turns the compressor clutch on or off with a simple electrical signal and works much like the relays that control fans and blower motors. The HVAC Pressure Switch has two functions. First, it stops the compressor from running dry when it experiences low pressure. Next, when it experiences high pressure, it cuts power so the hoses or seals do not burst. The benefit for Ram occupants is the avoidance of fault codes and sweaty rides. The earlier model years of the Ram 3500 applied a single function cycling style HVAC Pressure Switch with a low side protection focus. Later model years of the Ram 3500 trucks switched to a dual function style that monitors high and low thresholds. As a result, the component count was reduced while overall reliability was improved. The fact that this HVAC Pressure Switch is a known weak link makes it a proactive replacement so that the rest of the climate chain doesn't get silenced and the whole 3500 remains cool.

Looking for affordable and high-quality auto parts? Then you have already arrived at the proper online shop. We offer all Ram 3500 HVAC Pressure Switch at great affordable prices. Moreover, all genuine Ram 3500 HVAC Pressure Switch come with a manufacturer's warranty. In the long run, you would realize you have saved a lot of trouble and money with OEM parts from here.
