Just noticed today that left turn everything doesn't work. No previous electrical issues and other than the fuse issue, nothing current. Its a 10A fuse and is usable until it burns open.

Seems simple but wonder if someone may've experienced a like issue before I start fixing it until it breaks.

TIA, Shummy ~

Well my 98 just started to do it and it was the trailer wires worn through. But yours should be separate fuses for the trailer but maybe crawl under the truck and check the wires. Does it blink or just stay lit up then blow the fuse.

No, no warning or pre indications. The flashing indicator in the inst panel shows it working but the indicator in the side mirror doesn't, a chk of the front left and rear left lights find them dead. Wondering about the switch itself ~ ~

Update ~ went thru the last of the 10A fuses and have an 15A temporarily installed and seems to hold so far. Will get some more 10A in the A.M. and start tracing wires.
