Ouch... you have some work ahead of you.

#1 - Don't know
#2 - Don't know
#3 - ABS Accumulator. This is a device in the Hydraulic system that stores hydraulic pressure created by the hydraulic pump. When this device has failed, the pump needs to make up the pressure all the time. It's not designed to run all the time so it's recovery is not fast enough to prevent hydraulic pressure from dropping for a moment when brakes are used. This creates a momentary period when the ABS pressure switch flips the lights on. This behavior is very stressful for the pump to have to run so often. It would be a good idea to get this fixed fast. I would also suggest changing out all the brake fluid while your at it. Also check the rear brake calipers to make sure the lower slide pins are not frozen up.

Thanks for the reply. Just so I am sure I understand, that thing in the diagram called the accumilator is bad, correct??
Where can I find a new one and how much??

Prior Remanufacturing sells them for around $99.00.


Note that this is based on your description. It may not be your only problem. The nice thing with Prior is that if you buy the accumulator and you find further problems, they'll can rebuild your ABS master cylinder assembly and will deduct the cost of the accumulator towards the cost of the rebuild.

As far as question number one, I believe it is your cd player. The one in my '91 did that and I had to heat up the cd player to get it to work. As long as it's hot, it works. I think they had problems with the electronics in the cd players. See if anybody will verify that though. Brandon

I know you can install an aftermarket head unit on the JBL system and use the stock amps. Or you can bypass the amps
and use the radio's built in amp.

Is there a way to wire an aftermarket radio with an internal amp so both the radio amp and JBL amps combine their power??
