I've come across an issuse with my brake lights. The only thnig different that I have done is replaced my battery. Later on that night I noticed the brake lights stayed on. checked the brake petal switch and seems to work. somehow the Third brake went off but not the ones on the bed. So I disconnected the battery and fixed. Reconnected the battery and so far so good. The next day the lights again came back on. talked to a shade tree Mech and told me maybe the computer can have a code or needs to be reset..? he had an issuse with his car where the windows wouldn't work till puter had to be coded. True or not I don't know.
03 Dodge 5.7 Quad, Never had nothing happen before since I have gone thru two batteries before. Also my two front doors don't open with the keyless remote. back two do.....
Any suggestions.....

 

Sounds like the pedal switch to me, for your brake light issue.

Or it could be your pdc which could also be an issue with the locks. But that could also just be a bad connection. Do the power locks work from the door switch?

 

Nope, door locks don't work from either door switch or remote. I did check the connections. Wells as of yesterday afternoon, brake lights are off, so let's see later on
