I have a Dodge ram 4x4 2010 5.7.. My 4 wheel low light blinks when switched on but it doesnt seem to egage. 4 wheel high does engage and works fine and the light doeasnt blink

I typed this on a phone sorry for the spelling errors

Flashing means the conditions haven't been met to switch into the low gear. You need to be going under 5 mph and in neutral to shift into the lower range on these trucks. This means, if you need low 4, pull over, shift into neutral, then engage the 4 low. Should work from there.

put it in neutral switch to 4low then put it in gear and 4low light will illuminate on the dash along with the stability control off

I always stop and put it in neutral never put it in 4 wheel drive when truck is in motion
