I never said the idle problem couldn't be the PCM. I said ALL of your problems are not related to the PCM and I doubt any of them are caused by a faulty PCM. The windows certainly have nothing to do with a PCM.
An alternator being replaced 2 years ago means absolutely nothing today. As I already advised, you need to get the codes read first and post the NUMBERS here. If you have an alternator failing, replace it.
