Hi Jack
the windshield turned out perfect!
Are you planning to run wipers or just rainex?

thanks for sharing.

I installed the CTS wiper system.

I was working on the right side window regulator and needed to cycle the window up and down and I don't have power to the motor. There's power to the plug, but no function. I got my multimeter out to start checking and found that the batteries had leaked and ruined it. Balls!

I ordered another and moved on to other things. I got the seat belts mounted and the pretensioner plugged in. While I was messing with the SRS, I tackled another problem. The CTS had side curtain air bags and since I have a lift off roof, I can't use them. No problem, there are plenty of other explosive devices left to pummel me from every angle at near light speed in the event of an accident.
You can't just leave an air bag connection disconnected. The BCM (body control module) pings all electrical circuits constantly to monitor functionality. It expects a specific reply from each circuit. In the case of the side curtain air bag, a functional/nondeployed bag will return a signal of 2 watts - 2 ohms. If the BCM doesn't receive this reply it will throw a trouble code - SRS faulty air bag.


So, what I did was remove the side curtain plug from the harness and installed a 2 watt 2 ohm resistor across the two wires. This tricks the computer into thinking that the air bag is still there and functional. Different vehicles have different requirements. Also, different systems within the same vehicle will have different requirements.


DISCLAIMER: I don't recommend tampering with SRS systems. Beside being illegal, it's dangerous. I have no legal issue in this application because the vehicle is titled as a 1949 Cadillac. Safety and emission requirements are determined based on the year of the vehicle. This car didn't even come with lap belts. Anything beyond that is a bonus.

Next I needed to make a cowl closure. I have the one from the CTS but it doesn't fit. The firewall is from the CTS so some of it fits but it's wider and doesn't even come close to fitting up to the Buick windshield. I'm using some ABS sheet to form the new cowl along with some scavenged pieces of the CTS cowl. For example, on the CTS cowl the grommets and seals around the wiper arm shafts are injection molded rubber that is merged into the ABS during the molding process. Very clever, I don't know how they do it but I've seen it on other late model automotive parts.

You can see them in the pictures below. I grafted the grommets and the depressed area around them that clears the wiper arms.
I still haven't decided whether I'll use this as a mold, or if I'll just laminated the ABS with carbon fiber. If I just use them as molds, I'll have to cut these grommets out and install them on the carbon fiber parts. I'll probably just laminate the ABS and use them as is.
This one needs a little sanding and detailing, then it's on to the right side.

Jack,



When I got out of the injection molding business there were three general approaches. One, insert the rubber part in the mold and inject the ABS around it. Two, use a second mold, just coming out were machines that injected two different "plastics"






FWIW
