Not a common problem. Your leak is probably coming from the steering rack return hose to the pump, at the location you note (the pump is at the other end of the engine). It may have been damaged from road debris. You will probably have to replace the entire hose. Be careful - the smallest amount of contamination in the fluid circuit will screw up the rack, and that is big $$$ to replace.

No the torque converter clutch solenoid won't have anything to do with it . More then likely it's the internal mode switch . This tell's the computer which gear is selected , then the PCM energizes the correct shift solenoid . The PCM will send this info to the instrument cluster over the class 2 serial data network . The instrument cluster has a microprocessor with logic programmed into it. More then likely has DTC'S - diagnostic trouble codes stored in one of the computers on the vehicle . Your best bet , take it to a qualified repair shop . The internal mode switch (IMS) is a sliding contact electrical switch assembly that corresponds to the PRNDL position selected. Each of the PRNDL positions has a unique ground pattern on the four wires from the PCM. The IMS consists of two major components: The housing, which houses the tracks and makes up the stationary contacts. The insulator assembly makes up the moving contacts and is linked to the detent lever. The range detection is accomplished by securing the moving contacts of the IMS to the detent lever. When the driver selects a PRNDL position, the detent lever inside the transaxle rotates. This slides the IMS moving contacts which in return grounds the four wires in a unique pattern for each gear selection corresponding to the PRNDL position selected. The IMS is electrically connected by five wires (four of which the PCM supplies voltage to and one wire that is a common ground) to the transaxle pass through connector. PRNDL Display The IPC is equipped with a vacuum fluorescent (VF) PRNDL display. The IPC PRNDL information is received from PCM via class 2 serial data message. Turn OFF the ignition. Install a scan tool. Start the engine. Place the gear shifter in the following gears: • PARK • REVERSE • NEUTRAL • DRIVE Observe the IMS parameter in the powertrain control module (PCM) data display. Does the scan tool indicate that the IMS parameter is the same as the PRNDL display for all gears?

Hi, you have to replace the cigarette lighter fuse....

Look at all the body and engine grounds, there are some you may not be aware of so it would be advisable to look them up.

The mode door actuator is bad . 2000 Cadillac Deville mode door actuator replacement

With a noid light . 9pc Electronic Fuel Injection Signal Noid Lite Tester Light set GM Ford... or you could use just a test light . Video's on youtube showing how.

If you disconnect the battery, in most cars this will reset all systems. However from your description I would expect that the problem is a faulty actuator

This is just a guess, but try disconnecting the battery cables for a few minutes, then reconnect them and see if you can correct it.
