Seat belt warning light & chime & intermittent wiper issues

Thanks for the explanation of warning devices. I thought it's something other than the GEM.

I called 8 dealers. The cheapest was $79.95 and the highest was $110.00 for the GEM scan. Not sure about the cheapest one since I never heard of them before, but it showed up on a dealer search of the Ford. Com.

I disconnected a connector from the RCM, so I won't accidentally set the airbag/pretensioner off. I jumped the BRN/LT BLU to the BLK while the ignition was "ON". The seat belt warning light came on, but no chime. I assume I didn't get the chime because I jumped the 2 wires when in "ON". To induce the chime, I have to jump the wires from "LOCK" then change to "ON". I'm gonna try from the "LOCK" to "ON" next and see if I get the chime unless you know it's not worth doing so.

Fordparts. Com says the replacement "Seat Belt Buckle Assembly - (Front Seat); Black - includes pretensioner, attaching hardware W709862-S430 not included. (Left)" is about $200. If there is something wrong with the pretensioner say it was deployed, the RCM's gonna give me a blinking light code/airbag light constantly on, yes? If the issue is only the seat belt switch in the buckle not grounding, I'm gonna say I'm keeping the minimum of $300 repair. Thank god for the state of IN not having a mandatory inspection.

I'm gonna try to go to a junk yard and get a turn signal/wiper assembly.

"if the chime and warning light don't work". It's "IF". Some dealer said that they may not scan the GEM at all depending upon the problem. I specifically asked for the scan, but they didn't give me the quote. I told these dealers "forget you." I don't understand why you keep saying get it scanned since some of the dealers might not do the scan even if a customer specifically asked for it. I guess I have no choice but to test the "LOCK" to "ON" jumping since it was unanswered. Also, I guess you don't have an answer to a question of if there is something wrong with the pretensioner say it was deployed, the RCM's gonna give me a blinking light code/airbag light constantly on.

I appreciate diagrams and all, but if an answer to a question is trivial, then I will ask for my money back since both of us wasted both of our times. No gain to either party.
