I have a 2002 dodge ram 1500 4X4. I installed an airram CAI a while ago. I had read that I should have reset the pcm after I installed it so I decided to try resetting it to see if it made any difference. I did this buy disconnecting the negative battery terminal and turning the key to the start position for 15 seconds. Then I removed the key and reconnected the negative terminal.
The problem I am having now is that whenever I start the truck the headlights and brakelights come on and the wipers and turn signals do not work, also I cannot brighten or dim the headlights. Does anyone have any ideas what may be causing this.
