Dunno if a Jimmy fits in the autos or the trucks section so I'll xpost
A friend is looking at purchasing a 91 GMC Jimmy with, among a few
other fixable problems, is a temperamental digital dash. According
to the owner it has a "short" in it.
I've been told to stay as far away from digital dashes as possible
because they are a huge pain in the *ss to get working as you can
never quite find the problem.
There was always a problem with the digital dashes, if you find a truck with
one bad, usually the gas gauge will flash wrong, the temp wont work or
sometimes the odometer will flash error. Good luck finding a good one at a
I dont know what causes the problems, I think it is a design flaw, because
I've never known someone to keep the same dash and fix it.
He can ship it away to get repaired. They'll just send him one that's
been fixed and will keep his as a core. My mother had a '87 Cavalier
Z24 about 15 years ago that went through digital dashes like they were
going out of style. I think it's just Chevy's digital dashes. My
uncle's '82 Chrysler Imperial's dash still works great. They're cool.
I wish more cars had them. In the '80's, a lot of cars were available
with digital dashes. I've never came across a car with a nonworking
digital dash display, except my mom's Cavalier.
Speaking of Chrysler Digital Dashes...
Years ago I was working at a muffler/brake shop and I had the occasion to
drive a Chrysler le baron or sumsuch to check out a brake problem.
Well, there I was driving down the road, alone, with the radio off so I can
listen to the car to see what's up with the brakes.
I made a turn and then I heard a "voice" say FUEL LOW!
That scared the livin' crap outta me 'cause I knew I was alone in the car.
I almost ran the thing off the road before I could collect myself.
Yea, I know, the TALKING digital dash, but it was the first one I had
Go ahead and laugh, I did...
That was the 'Voice Alert' system. It was a 21(?) point diagnostic
monitoring system (oil pressure, temperature, voltage, fuel level, door
ajar, etc.). Chrysler had it as optional in cars with non-digital dash as
well. It was either standard or optional in the E Class, Lebaron, Laser,
Daytona, Lancer, etc.. It's a pretty good idea to have a voice that tells
you if your car's getting hot or if oil pressure is low. It might save an
engine from becoming toast. Older drivers would especially benefit from
it. This reminds me -- I want an '80's FWD turbo 2.2 pocket rocket! Omni
Shelby GLH, Daytona Turbo Z, etc.. Or a Shelby turbo Charger. These cars
had personality. I had an 1985 GLH Omni (Goes Like Heck) in the early
'90's -- a non-turbo blue one with the swiss cheese wheels. Even the non
turbo models were fast; had a HO engine and different gearing over stock.
The Shelby models were quick, no doubt I had one till someone liked it more
than I did. But the 2.2 carb model wasn't that fast.
Car and Driver did a shoot out, fastest production car in the late 80's or
very early 90's.
IROC Camero, Firebird, Mustang 5.0, Corvette(Chevy made them put a roll bar
in it, and
they locked 6th gear out) Buick V-6 Grand National, and the Dodge Shelby
a Turbo Lancer. Ford got their feelings hurt bad.
Off course the Vette came in first, Ford dead last. Oh I almost forgot, the
S-10 hot rod
all wheel drive, blew the Vette away off the line, and only got beat by a
car length in
the drag test portion.
As to the Voice alert, who could ever forget the constant nagging "A door is
ajar, A door is ajar..."
as you under the dash working on something.
The Omni GLH was fast compared to most other econoboxes of its era. Most
economy cars of that era had 60 hp 1.5 liter engines, but the Omni GLH had
a 2.2 HO, along with optional turbo. The non turbo car put out 110hp and
the turbo version put out 145hp. That was a lot of power back then, esp.
in a small car. The hp to weight ratio was why the GLH was able to hang
with the Mustang/Firebird crowd. Then later versions had either Turbo 1 or
Turbo II specs. And then a lot of people tweak these cars with bigger
exhausts and upgrading to Turbo 1 or 2 specs. The highest stock hp of an
Omni GLH was 175. The 2.2 was a great engine. Real solid.
I had a '90 with the digital dash and had to have it repaired 3 times, once
under warranty. IIRC, it was about $400 a pop at the dealer. I wouldn't
reccommend one unless you can figure a way to convert to the non-digital
