93 dakoda elec. problems

I have a 93 dakoda 4x4 with 270,000 km on it..The other day all of the indicators except the spedometer stopped working. Anyone have any idea what it is? maybe a fuse or something? I really need to fix this soon and cannot afford a garage!

start the truck and if it still happends slap the to of the dash. my 2 daks did that and still do but i smack the dash and everything gets better.

i have a 93 dakota that does the same thing. trying hitting the dash, not too hard, to make the connection happen. works for me until i find time to fix it.
