Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. The most common cause of multiple issues like this is a voltage problem. You need to start by checking the battery. If it is low and does not pass a load test then that is the problem. If the battery is fine then the negative battery cable connections need to be checked. If those are also fine then you may have a failing integrated control module. I hope this helps. Please let me know if you need more help.
