Recently purchased my 04 ram 2500 v8 noticed the check engine light never came on when I turned the key so I bought a scanner and ended up having a code p0420 that’s just another problem.. also did the gauge test holding the trip and turning the key on and quite a few lights do not come on along with the check engine light unfortunately I have no idea to why the check engine light isn’t coming on or Any of the other lights if anyone had this problem before and has a quick fix please let me know thanks

 

I'm thinking that either the bulb for the check engine light was taken out or it's simply dead...

 

I pulled the cluster already and the bulb cannot be changed I really don’t want to buy another cluster

 

Consider possibility that it was intentionally disabled.
Look around the cluster for something unusual, like a cut wire or burn in a board. I am not familiar with the wiring for the MIL.
If you bought from a dealer you could let them know they sold you a car with a malfunctioning light and ask them to check it for you. State laws vary on this matter and you would need to check how your state handles these problems.

 

well I’m from New Jersey im about to fail inspection and bring it back to them like I thought the vehicle was ready to go?

 

Where did you buy it? Do they not have laws that require dealers to inspect (state inspection) vehicles before sale?

 

nj wholesale car seller it just passed pa inspection for 2021 no idea how but I’m in jersey

 

If you have lemon laws then use them. Complain about the issues you're having to the place where you bought it from, as long as you didn't buy the vehicle in "as is" condition.
