Suit is short please remove the switch problem

The better scanners can hook up to a connector port and diagnose the air lift system. This saves diagnostic time and the expense of replacing good parts. The trigger for your air ride system is probably one that you would not imagine. The trunk lid switches and the door jam switches tell the car that it needs to lower or pump up the system. The idea is that you want the car lower to load passengers and to lift things into and out of the trunk. When these trigger signals reach the solenoids it is their job to add or release air. At least your pump is working. The diagnostic scanner will tell whether the solenoid is bad or a signal is missing to the solenoids. There is a master dump valve in front of the drivers wheel well to lower all ends at once.

A lot are difficult to adjust correctly, but most are easy to replace.

Since you have located several components in your wiring you must be using a diagram. Look at your wiring diagram to see if the feed fuse has anything upstream that would cut off the power (like a relay or the ignition switch). If not, then the problem must be that the power from the feed fuse is not being turned off downstream. There must be another relay or the ignition switch is bad and keeping the power on. If there is nothing listed you have a melted wire or connection which is bridging power to the accessories. If your vehicle has a trailer plug, check the wires. Something is feeding power to a wire that normally is off. Sometimes I disconnect the battery and check continuity on the wires. Off is suppose the be Off so that some wires are not suppose to be grounded to complete a circuit. Its a different way of looking at whether some wire is grounding. In simple terms if a pigtail is disconnected and the wiring is showing continuity there is a problem.

Hey Joe, are you sure the cam moved? The cam is usually held in place by tension placed by the lifters/push rods/rocker arms/valve springs.. Check to see if the cam sprocket will only bolt up in one position, if so, you should be able to time everything...

the heater is a long plastic box and the mixer door is inside of the box. The stepping motor controls the door.

the rpms drop because you are adding more of a load to it. it should level out after a few seconds.
