I have this in mind:

Also if I connect the normal wiper connections to the motor I get smoke coming out. I can see that the wiper case ground goes to the heater blower ground which not existent on this car but is there a resistor at the heater blower ground wire that changes the resistance of the ground or what makes the heater ground different from the chassis ground.
When I changed my 72 to a Classic AC system there was no mention of doing anything with the ground wire when I removed the blower and my wipers till work fine on the 72.
I have read your articles on wiper motors and tests but still have the problwm.
So the question is how do I properly ground the motor case and how to stop the smoke form coming out.
What am i missing?
Thank you for your help.

Simply enter your year, then search with one simple word... "Wiper" "gauge" "temp" and so on.... If you search and read, you can in most cases solve your own problem.

I'm sorry, but the request for wiper motor help and individual gauge issue help has exceeded my human ability... I'm wiper motored and gauged out.

The help is there on the tech site.... the only issue is you must be willing to read the info and there is plenty there and if you do, you'll find your answers.

You are only 4 nuts and a clip from having the booster out, to do it any other way would be from the bottom and removing the A shield off the frame. The only issue is to get to the bolts for the A shield you have to remove the rocker molding (which can be a royal pain). I'm not even sure you can get it out this way either....

I have a question on my 76 lower driver dash.

I took pictures as i removed it, and looking at the aim, but i cant seem to get the new one to fit far enough back to correctly fit the shifter console.

there is still about an inch the right side needs to go back for the shifter to line up with everything. Its showing on the column shaft too, its just a hair to far forward but i cant find where to needs to move. Its also seems to be butting up against something because its solid. The tach and speedo buckets have both cleared the column support bracket, but are pretty much resting on said bracket now.

The car just went in for alignment so it will be a few days before I get it back but was wondering if you had any ideas of what that might be?

I've given the diagram a look (using Dr. Rebuild for Early 69) and prior to changing the old safety switch the door worked fine except that it would close on the wipers before they would park. I installed a new one. I placed vacuum on the middle port on the new switch and it held. The old one did not. So I put the new one on. The only other new part is the light switch. The reason I focus on the switch is because that's the part that seems to be creating the problem....and tracing the diagram seems to be the "check point" on whether air is released or not. Right? I second guess this to because this happens about 20-30 seconds after the engine is shut off which prior to any changes, and some post up, I described a release of air about at that time. Hmm.... your help, as always is much appriciated.
