1987 C4 intermittent dash cluster

[TomPaterson]

Hi,

I'm looking at the possibility of importing a C4 from the USA. The advert states that the instrument cluster has an intermittent issue, and sometimes it
will work, and other times it won't. Any advice on who I could send the dash do for a refurbish, or where I get a replacement. I'm trying to find out if
the car has cruise control or not, as I need this info to proceed.

Many thanks.
Tom

Not sure if reconditioned dash clusters are available here in the UK, but they are in the US. Priced around $300 ish . Assume you’re talking first generation 1984-89.
I only ever bought one over a good few years ago, arrived and worked fine.
Quite a few sellers on eBay.com

If the electronics of IPC is bad, then it is always bad and not random on or off
Have you thought that this is a wiring or their pins from the IPC to the CCM
or simple cracked solder joints ?

Be a shame to spend lots of money and time waiting for a new or repaired IPC to find out
it is not the problem

There are quite a few C4's already here in the UK before you ship one over.
The early digital dash cluster is fairly easy to repair yourself if you can solder.
I rebuilt my 86 dash a couple of years ago and converted it to LED.
The most common cause of an intermittent cluster is the 12 pin connector between the two internal circuit boards, easy to replace if you can solder.
The best place for information and spares for them is here:

They all had cruise control.

I do have a repair manual for the early dash, which includes diagnostics. I’m considering importing, as I can’t find the C4 I’m after. I can’t post in the wanted section yet, still a fairly new member. I’m after a 85-90 C4 with pre facelift dash. Prefer it in white, red interior, auto with the TPI engine.

Have a look at the Batee website, none of the manuals, even the genuine GM shop manual goes in-depth into the digital dash.
