Hello one and all. First off great message board I have learned alot from here and recommend it to my dodge friends.
I have researched this board in hopes of finding an answer.

I have a 2002 Dodge Ram quad cab with a 4.7l engine. I recently change my right side rear tailight, Upon doing this i have no dash lights. I have the mileage indicator asnwell as the factory radio lights just the clock no dials . I also have the upper console trip mileage indicator which works with no problem. I have checked all the fuses and replaced any that needed to be replaced. I am at a loss right now.

Second Issues is that when I drive at 10 -20 miles an hour i hear a whooping sound from under the truck . A mechanic said it was a pinnion gear however i dont know. I just had my ball joints replaced in the front of the truck. Not Cheap .

Lastly My ac works awesome so long as the truck is moving but when i get to a red light or have to slow down the ac blows hot air until i can speed up again.

I really need some help with these issues and the local dodge dealer is no help at all. Any help would be greatly appreciated.
Thanks
