Same happened to me on my 74.  Ended up being the fuse connectors.  Over time, the connections get a bit lose, I pinched it closer together and solved the issue.

Put the year of your car in the signature.

Click on your username in the top right corner of the screen. 

On the left hand side of the new screen, you will see Signature.

Good idea. as he @Dolfinz not jet did that.. after you click on your name you have to click: ACCOUNT SETTINGS and THEN you see that list and click: signature!

Put in type and year of your car and your good to go!
