On the non op turn signal, in spite of best attempts sometimes a satisfactory ground is just not doable thru any oxidized pot metal pieces in the grill. You may need to fasten a ground wire directly to the lamp housing or directly to the socket and then run the other end out and fasten it to a good clean spot on sheetmetal.
On a front socket the turn signal filaments are by themselves and if the fiber plate at the back of the socket holding the contacts got wet and deformed one of the bulb contacts could also be at fault. Can also happen at the rear but on the rear sockets that issue is easier to spot because the brake lights would also be affected.
There is also a possibility it is not a ground or bad socket. Sometimes it is a problem in the switch. Oxidation on a single contact can happen or the phenolic supports the fixed contacts are embedded in can warp and allow one or more contacts to drop down and not make a connection with the triangular contact bridges in the sliding portion. If a new ground does not help you may need to take the switch apart...
Here are views of the switch. The extracted circuit has been posted before but if you missed it, posted again for reference..
