front turn signals not working

I have a 2005 Saturn Ion and cannot find why only the front turn signals will not flash when using turn signals or 4-ways. The dash and rear flashers work. Under the hood the connections, sockets and bulbs appear good and clean. Have power to through the connector and to the socket for all circuits except the flasher circuit. I do not have current coming through the light blue wire to the connector. Does anyone have a suggestion to where I can look next?doityurslf

The left front signal uses a light blue wire and the right uses a dark blue wire. The wires start at the x3 connector of the BCM under the heater controls. Light blue wire in cavity 44 and dark blue in cavity 46. From there they go in and out of connector plugs in the underhood fuse box before they go the appropriate lights. sparky

Thanks. I'll check those connections.doityurslf
