1988 GP Digital Dash Woes

[88GPSE]

I just acquired a 1988 Pontiac Grand Prix SE. I just completed a new plugs/air filter/o2 sensor tune-up on it and it runs a lot better.

 

It has a digital speedometer that does not work. I tried resoldering parts inside per a search on this board, but it still does not work. What is a good alternative to get this speedometer problem fixed? It's primary use is to commute from Southern PA to DC Metro 3 days a week, and the Maryland Mounties like to sit... and I don't think a broken speedometer is going to be a viable excuse for getting out of a ticket.

 

I'd like to stay digital, but what other car's clusters will work in this car... until I can get the digital stuff refurbished?

you could try the speedo from another dash. i've got a junk one. you pay shipping and i'll send you the speedo

I have a cluster from my old 88 GP SE... it's got 280,000km on it (about 168000miles)

 

$20 + shipping

WTF? That systems monitor looks space age-y. Here's my old one:

 

 

Also, if you buy that cluster from C-Bad, you'll have to just swap the speedo module. The rest is in metric units rather than imperial.

it's them damn cantadians.

 

"Canada, America's hat." don't know why i thought of that, but there it is

That made me ROFL.

I'm having major deja-vue of this thread. CBAD, that systems monitor is from one of the old dust buster vans. I would like to buy it if the other guy doesnt... i'll PM you about it. For the other guy, i may have another digital speedo for you. I have one in good working order, im just replacing it with one with mileage that reflects the actual, as i did a swap into a 92.

oops you beat me to it Ross

I forgot the Trans Sport had a Grand Prix-ish interior.

[THe_DeTAiL3R]

Yeah we went over this before about it looking like it's from a Transport.. lol

 

Are you SURE that it isn't the same as imperial? I mean I was able to just flick the button to go from MPH to KM/H same for the odometer. Only real difference I see is that the temp is in Celicious rather than *F.

 

Ross you have a PM.

very, very similar interior. I wonder if you can add a first gen HUD and DIC to a transport as well.

 

The Trans Sports didn't come out until 1990, and the digital dash was discontinued in 1989... so who knows?

[stockgp]

celicious. sorry that made me laugh.

[stockgp]

from what i understand, the hud operates on it's own, doesn't it. it gets it's own vss signal and ses light, i think. if so it should work with the digi dash

[THe_DeTAiL3R]

1988 didn't have HUD as an option anyways, so I don't think it matters (unless you are putting it in a different year maybe)

No it doesnt.... I was speculating on adding a first gen GP hud and dic into a transport.

LOL... that sure would be interesting considering the huge angle the windshields are!

Anyway, back onto the subject matter.
