87 Silverado dual tank issue

I have an 87 Silverado and recently I have noticed and issue when trying to switch from the right tank to the left tank. When I flip the switch, nothing happens. The right pump continues to run and the guage still continues to read the right tank. If I rock the switch several times it might switch to the left tank. Is this the switch or a wiring issue? I have checked the connections and wiring under the truck and everything looks good. Have not had a chance to check the wiring in the dash yet to the switch. I am leaning towards the switch but I am unsure. The last time I had a problem with the switch was 14 years ago and it fell apart literrally.
