Newbie to the board, so if this needs to be transferred to a different form please do so.

I have picked up a 78 Blazer and have started to get it fixed up and have run into a couple of problems.

1. The windshield wipers - When the wiper motor is connected, the wipers will run a full speed. When I try to turn them off at the switch, they will turn off for about 20 sec, then start back again. I have replaced both the motor and the switch. Any other ideas?

2. The speedometer and odometer don't work. I have tried to located the speedopoter cable from the firewall but can't fine it. Where does it come out at?

Thanks for any help
