What is the correct bulb for the glove box on a 70? I tested the socket with a light and there is power there but the bulb wont light. It has a 14V 7 watt bulb. I replaced it with a new one and still wont work.
It's a #1893 bayonet bulb.
If the dash pad is still off you can pull off the connector that has the orange (constant +12v power) and black (dedicated ground) and check the connection for power.
If the dash pad is on, you can remove the Phillips screw and try to carefully lower the bulb holder and pull the wiring down with it and check for power. Just don't loose the wiring if it wants to pop back up, then you'll have to pull off the pad again.
The last one I worked on was a friend's 70SS. I pulled the holder apart (carefully) and did a driveway rebuild of it right there and then. The spring inside developed corrosion on the end and wouldn't allow the light to receive power.
