I'm looking for some serious suggestions as to what might be the problem. My turn signal indicator lights flash twice as fast as the turn signals. Everything works fine they just flashed twice as fast as the turn signal. I keep getting codes b2141 and b2146 which are left and right front turn signal output open. I tried clearing these several times and one time they both had a c after the 2141 and 2146. I never saw that before. Now they just read 2141 and 2146 but they won't stay cleared. I checked the fuse everything is good. Any suggestions?
