How to service the A/C Switch and heater controls on 2000 Dodge Ram 3500 Van?

Connect the probe from your test set to the heater-A/C vacuum supply tube near the engine and position the test set gauge by the controls, so you can observe it from inside the passenger cabin. Turn the mode control switch knob to each position, then press it several times; each time, the test set gauge should quickly return to the 27 kPa (8 in. Hg.) setting. Presence of a leak within a valve or vacuum line is the cause if the gauge never turns off in the selected operation. Don't apply lubricant to the holes in the switch or to the plug itself, since this will cause damage to the vacuum valve; instead, just add a little clean water inside the connector for the plug and it should slide easily into the switch.
