Help!

Hey everyone I have a 85 F250 with a 351 my signals and fan for my heat will work when just turning on the key but when I actually start the truck these things stop working? My question is what are some possible reasons and where to look?

Thanks everyone in advance

After starting the engine, try wiggling the key cylinder. The key may not always return perfectly to the run position. See if that helps.

GRY/Y wire at the fusebox powers both circuits. Have a look at the photos in this post.
