Dashboards - I don't get it
Since the passenger airbag went off on my kid's '95 Bonneville he's
replaced the dashboard and seats. He picked up a clean console dash he liked at the boneyard, and bucket seats. His split bench seats are in my garage. Next week he's going to fit the driver's Pontiac seat into my '97 Lumina, which has collapsed on the left side. Every Lumina seat he's seen in a boneyard is likewise collapsed. Can't get them from GM, but an upholsterer can fix it. I spent some time watching him replace his dash and seats. Dashboard is a huge job. Not for the faint at heart. It got me to thinking why dashboards aren't designed with multiple segments - maybe 3 pieces. If you've ever replaced a heater core or instrument cluster, you know what I mean. You've all heard the dreaded words, "Have to remove the dashboard, so you're looking at $6-700 right there." There's plenty of connection brackets behind the firewall to secure the pieces. Only reason I can think why a dash is one piece is the cosmetics of an uninterrupted line. A windshield-length, fairly easily detachable piece could cover segment lines if the public wouldn't go for 2 simple gap covers. You can do a lot with modern plastics. Wouldn't look bad at all. Besides the common issues requiring pulling the dash, now, with airbag deployment wrecking a dash, you would think at minimum, the airbag would be in a dash segment so you don't have to replace the entire dash. Maybe I'm missing something. Followup to the airbag going off for no apparent reason in the Bonnevile. When my kid was walking on the floor after he pulled the passenger seat, he heard water dripping on the garage floor. His walking had popped an underbody drain plug. It's directly under or very near the airbag control module, which sits on the floorpan under the carpet there. Maybe a cup of water drained out. I felt the carpet over the control module and it was dry. He'll find where water is coming in when he puts it on the rack at his work and fix that. He didn't pull the carpet to get at the control module. It's just a bump in the rug now. Has a bagless car now, new steering wheel, new dash with console, and bucket seats. Cost him about a hundred bucks. And lots of labor, maybe two 10 hour days this weekend. And a full workday at the boneyard. But he loves doing this stuff. --Vic |

One big mold is often cheaper than many small molds. The assembly of one big piece generally costs less than the assembly of many small ones. Essentially it's just designed for assembly. I can see how it all goes together in the factory. Easy to put together... a pain to take apart. What really should be done is design for service where the components under the dash can be replaced without removing the dash. I replaced the heater core in a mazda once... manual said to remove the dash. I didn't. The whole thing would have been relatively easy except for the fact that one of the pieces in the way... part of the duct work as I recall had closed slots instead of open slots. With open slots it would have come off the studs easily without removing the dash. I broke bridges at the end of the slots and removed it making the heater core accessible. > Followup to the airbag going off for no apparent reason in the > Bonnevile. > When my kid was walking on the floor after he pulled the passenger > seat, he heard water dripping on the garage floor. > His walking had popped an underbody drain plug. > It's directly under or very near the airbag control module, which sits > on the floorpan under the carpet there. > Maybe a cup of water drained out. > I felt the carpet over the control module and it was dry.

Think I read the evap on my Lumina requires pulling the dash. As you say, the shop manual isn't always the best place to look. I was ready to junk my Lumina when I read the shop manual procedure for replacing the lower passenger motor mount, which was almost gone. Found a procedure on a Chevy forum which took a tenth the time and had none of the "gotchas" in the shop manual procedure. > >> Followup to the airbag going off for no apparent reason in the >> Bonnevile. >> When my kid was walking on the floor after he pulled the passenger >> seat, he heard water dripping on the garage floor. >> His walking had popped an underbody drain plug. >> It's directly under or very near the airbag control module, which sits >> on the floorpan under the carpet there. >> Maybe a cup of water drained out. >> I felt the carpet over the control module and it was dry. > >Could be the AC condensation line.

Old joke about the "car being built around the heater core"... I had a '97 Chrysler LHS. I was working for a Toyota dealer, but my shop was located in the neighboring Chrylser dealer. I filled the system with a "blow up can" of R-134, and it actually blew cold air for about 2 days, then back to hot... One of the real good techs in the Chrysler repair shop said they would have to replace the core at the exchanger, and that would mean removing the dash, and even with my discount would be about $2500. That car made a REAL nice winter car... |

The arm swings into the vehicle body, locates the assembly, then the line workers buzz in a few bolts, hook up the connectors, and pop a few covers on. The ones I saw in action took, I'm sure, less than a minute each. -- Tegger |
