...eine hohe Warscheinlichkeit betrifft den "striker sensing switch"....das ist der kleine schwarze "Mikro-Schalter" direkt oben an der Zuzieheinheit der 86 - 91,5er Modelle, am "Schnapper", wo der die Öse des Kofferraumdeckels ins herunterfahrende "Schloss" einrastet/schnappt.....
...es ist nicht immer gleich der Motor...oder die Verkabelung...und dieser Schalter wird sehr gern übersehen....
...der ist nicht mit dem Motor-"Umschalter" ("reversing switch") unten an der Einheit zu verwechseln...auch eine beliebte Fehlerquelle, auch nicht mehr als Neuteil lieferbar...
Striker Sensing Switch
Troubleshooting: When the striker-sensing switch begins to wear it will operate erratically. Sometimes if will fail to sense the latch hook, thus failing to energize the motor to pull the hatch or trunk closed. If you have to fiddle with the switch to get the unit to power down, then it is time to replace it.
Description:
It is a small black plastic switch, mounted next to the latch with one screw.
Function:
The function of the switch is to sense the presence of the hatch hook, and power the unit down. When it reaches the end of the cycle the "reversing switch" will be flipped by the lift rod and turn off the unit. The unit will remain powered off until the latch is released either manually with a key or by the hatch solenoid. At this point the striker-sensing switch will sense open (because the hatch hook is no longer pressing against it) and the unit will be powered up until it reaches the end of the cycle. Pressing the switch again during mid-cycle will not stop it from continuing the upward travel. If the hatch hook is not moved far enough away from the latch when released (often a symptom of weak hatch struts), then the latch may re-latch onto the hatch hook as it powers up during the up-cycle. In this case when the unit reaches the end of the cycle (heard by a click of the reversing switch being tripped by the lift rod) the striker-sensing switch will now sense the hatch hook and IMMEDIATELY return the unit to its down position.
...dieser Schalter (im Bild oben links) ist nicht mehr (separat) orderbar, außerdem hängt ein großer Teil des Kabelbaumes hinten dran...
Topdown Solutions bietet überholte Schalter an...
