PCM doesnt work......sometimes
I have had my car since May and this is the third time my PCM has stopped working . I get a white screen, hear the amp clicking on and off and then it just goes black. After awhile the problem goes away...Anyone ever heard of this?

Ditto for NorthVan. About a month before by battery went out the PCM had a mind of it own. Since the battery change 8-9 months ago not one problem.
Also keep an eye on the water level in the battery. I have to add water 2-3 times a year. A battery with low water will shorten it's life.

Sometimes a charge isn't going to get your battery back up to the required level. There is a chance that the PCM is fried, I have heard new ones are $2500.

I've had one get stuck because it didn't load properly. In that case, I used another disc to push it in a little bit further until it was aligned and then it was able to play & eject.

PCM failure in .1 997s is fairly common. Once they start acting up they don't cure themselves. The problems are intermittent and become more frequent over time ie; white screens, audio in and out, mysteriously changing channels. The clicking you hear is the MOST loop trying to power up through its cycle.
Couple of things you can do to assist and prolong having it replaced :
1- Do a hard reboot of the system. Pull the red 10 amp fuse behind the panel in the driver footwell( bottom row, 2nd to last fuse all the way to the right ) Let it sit for an hour and put it back in.
2- Always lock the car when not in use.
Not sure what year your car is or what version of PCM software you have but the dealer did a "patch upgrade" using 2 or 3 cds. This helped for about a month with no issues and then mine started acting up again.
I contacted PCNA in Atlanta looking for some gratus help but they declined any kind of assistance. In the end, the dealer stepped up and put in a new unit with a 2 year warranty for $1k.
Good Luck.

I don't know what year the OP's car is, but if it is still under warranty, I wouldn't hesitate to get it fixed by the dealer. I was quoted $2500 when I thought mine was faulty earlier this year.

My car is an 05 so its def. out of warranty. Im pretty pissed right now that sooner or later im gonna have to start shopping around for a new PCM. HatTricks reply to this post is exactly what mine is doing .
