Flashers, indicators, tachometer, not working--HELP!
 

Ok I searched around and found several threads on this subject but none with my exact dilemma.

I have been working on both my headlights and tail lights (new seals and lenses) and somewhere in the process have messed something up.

I replaced the flasher relay already because I thought I might have burnt it up by letting the contacts in one of the lighting housings touch--but to no avail.

Fuses are fine.

I get parking lights on one side and tail lights one one side, but not on the other, and no blinkers or indicator lights in the dash.

Also, when I start the car, the druck pressure light and battery warning light no longer light up nor does the tach function.

Any ideas?--I cannot open the tail light housings to check the grounds because they are rusted shut--but I know that is what everyone is going to say.

Any other ideas before I destroy the housings trying to open them from the back?

Thanks guys,

btw im in Athens if anybody is coming to town for a game and could have a look--beers on me
