Hello and thanks for using justanswer.com
Do the wipers ever stop in the middle when on any mode?
Ok this problem is usually caused by a bad park switch in the motor. I am curious as to where that poor connection was since we may have another wiring fault with the wipers. If you have a digital multimeter we can test the circuit. Also please check fuse #9 (30 amp) in the engine compartment fuse box. Let me know.
Yes the park switch will effect both intermittent and low/high speed. It could be the GEM although not very common. Unfortunately there is no adjustment to the GEM that can be done. Lets go to the GEM and on the blue connector pin 2 white / black wire is the park switch. With it still connected place the red lead of your meter to that wire and the black lead to ground. Turn the wipers on and the voltage should swing from 0-12 as the wipers sweep. Let me know.
The gem controls them differently when on intermittent. Let me know the results of the test.
Yes the diagram is different but the park wiring is the same.
Ok I still do not want to totally rule.out the park switch but it does sound like it is working. Unfortunately we will need a Jag factory tool to read if the gem is seeing the signal as the gem may be the problem.
Yes the park switch is inside the wiper motor. The dealer will need to see if in fact the GEM is seeing the park switch input and energizing the relay. Yes that is the fuse. I will double check the wiring diagram when I get back into the shop.
Fuse 8 powers the wiper relay and fuse 9 powers the park switch in the motor. When the relay goes bad we usually will lose auto wipers and the flick wipe so the relay should be good. We either have a switch problem or GEM problem but I still do not want to rule out wiring. Unfortunately without a Jag factory tool it will be hard to test the GEM.
