Another Trip Computer

J

John

GUEST
I know there is another long thread about the Denali/Escalade trip computer, however, I couldn't find a way to install this one and still keep a factory look so after a bit of research I found a trip computer that goes in the 2000 Blazer, Astro and Safari (and probably others) that is mounted in the OHC.

You will need to swap your OHC with the long console found on the pre '98 Chev/GMC, these are easily found on Ebay for about $50.00 to $75.00 or for those that have the sunroof you will need the one for the Blazer w/ sunroof which is the short version. The trip computer you can get from your favorite Chev/Gmc dealer for around $210.00 (cost plus 10% or I have also seen these on Ebay).

Though this one does not have as many features as the one found on the Escalade, it has a built in compass, outside temperature, used fuel , average MPG, instant MPG, range and average MPH and the best part that I like is that when installed no one can tell it's not a factory option.

My total cost was around $300.00 including the trip comp., the harness, the used console which I got at Ebay and the fabric to recover the console. Installation time around 2 hours.

John, how difficult was the wiring, does the trip computer perform all the functions it does in the Blazer, and does the color of the digital messages match the radio's? I'm with SimTechRay and other inquiring minds, how about some pics? Jason here is one I am sure will interest you, have you considered any Trip Computers other than the Escalade's? Perhaps we all have been trying to put a square peg in a round hole and not been looking for a different square peg. Way to go John.
 
john, where did you get the claddin over the wheels from? do you have a part number and price? any modifications have to be done to get them in place?
inquiring minds want to know :0:
 
Oh, Man!!!

That is sweet, sweet, sweet!!!!!!!!!

Next mod - coming right up.

I can get rid of one hole!
 
John,

What are the search words to find an overhead console on ebay (I've never bought anything off ebay before).

Thanks
 
(y)Great job John,
What area did you find the overhead consoles on ebay, here lately i have just been checking the avalanche section.
did you just go to part and accessories and put in chevrolet???
The harness you had to buy it plugged right into the bcm with no problems?? Since we already have a compass on the mirror or did you have to disconnect that one?
I really like this one and is affordable looks like it. May be looking you up for some more details when you get time. keep up the great work ;D (y)
 
John, i just checked ebay and they have 3 under chevrolet overhead console
1 for a 97 blazer
1 for a 98 blazer
1 for a astro van,,,,,,,,,

the one for the blazers says charcoal so they should be close to the right color, but it only say tempature and compass computer included, is this the one are how many are there? I emailed him to check, but don't know how honest he will be... if he thinks he may have a sell he may say anything.........45.00 is the asking price at the time. will wait for your response on question whether this is the right one.
thanks for the info

The 2002 Chevy Astro minivan has a trip computer. Would it work? It looks similar to your pictures (Chevy web site, 360 degree interior view, mounts in overhead console). I can't tell if there is a SR available with the Astro. Did you loose the outside temp and compass when you installed your trip computer? Oh, by the way, Chevy has an interior 360 view of the 2002 Blazer, with sunroof, with a trip computer - will this fit? (I have a sunroof - SR). The view seems to be a tan headliner with charcoal OVH console.
 
Rockslide-

I got them at the local Chevy dealer...P/N 15076368 @ $23.10 each. The ones on the rear are the same as the front, but you have to modify them for them to fit in the rear. I'll take one off and take pictures for you to see...give me a day or so.

Dandan-

Thanks for the complimments....You can search on Ebay using "Overhead console"...but be carefull, the only one that will work will be the one for the '96 & '97 Silverado, there are two types of OHC, one for the early model which holds the computer and one for the late model that has the cubby hole for the AC controls. I just did a search and there is only one coming up and it's priced @ $80.00 using Buy Now. The GM part # for the long one is 15047766 @ $230.00 from the GM Dealer. Sorry, I don't have a part # for the short version.

Zeeya2000-

You need the harness that plugs into the computer, the part # is 12102629 @ $31.37. It does not plug to the BCM, you have to tap into the wires coming out/in of the BCM and the mirror harness, BTW, yo have to make this harness longer. I disconnected the harness from the mirror, but I guess you could just cut the wires that are to be used by the trip computer and retain the auto dim on the mirror. Be carefull not to buy the OHC for the Astro/Safari, it will not fit the Av., the roof form is different. Also, be carefull 'cause there are 2 different computers, one is the trip computer that includes the compass and temperature display and there is another that is just the compass and temperature display w/o the trip computer. The part # for the one you want is 12376609 @ $210.98...the blazers came with both. An easy way to identify them is the one with the Trip computer has a MODE button and a US/METRIC button, the compass/temperature computer has the US/METRIC button and an ON/OFF button, however these are interchangeable... so be carefull when buying on Ebay. Also, the color of the OHC for the Silverado will not match the Av, I purchased the fabric @ PepBoys Auto...it's the Light Gray Overhead lining for $29.95, this is an "exact match" to the Av roof and it's real easy to recover.

Half-breed-

I'm not sure if the 2002 would work, according to the partsman @ the dealer he said the trip computer fits from 1999 thru 2002, however, while doing my research I found that there is a 2002 computer that is different, so be carefull, if I were you I would stick to the part # above or try to get one for the 1999-2001 Blazer.
Also, the color is not tan, but rather Light Gray (see above).

Hope I didn't miss any of your questions, if I did, please accept my apologies and shoot them again.
 
Half-breed-

Just went to the GM site and it does look the same as the one I have, however I have no way to comfirm if the harness will be the same P/N I listed above. You may want to check with your dealer....


Here is the link for the Long console on Ebay...
 
What and where is the BCM, and how do you find the schematics?

Click to expand...

BCM=Body Control Module, under the steering column to the left. As to schematics, the manual? or frankly XRover seems to have it decoded better than anybody out there. ;D
 
The Idea of adding a trip computer would be great. Thanks for including all the info, however, where does the Home Link part fit in the OHC with trip computer?
 
I finally did it!!

With John's help I put the trip computer in a diffeent overhead console and very pleased witht the results.

Total price - $300 and got a Homelink transmitter with the console I bought off ebay.

Next project - Jam up homemade bedslide!!!

thanks Maverick! (Really he went way beyond the call of duty to alert me to this opportunity)

Total price $145 + $30 (wiring harness).

Mod fever, catch it!

2002 SR-equipped Blazer is the donor,

* * * * UPDATE - this OHC does not fit the 02 Av * * * *
 
Before anyone asks - Yes - it is the trip computer as described by the seller on ebay, even though it has the on/off button instead of the mode button.

If the seller is lyin' Jackalanche and I will meet him/her and string 'em up by their toes!!!!
 
Okay... Now I'm upset ? :8: :8: :8:

Great find Jackalanche and Maverick. ?If you run across any others like that, PLEASE, PLEASE, PLEASE let me know. I also have a sunroof.

(just kidding about that angry thing)

absolutely wil pull a part #off of the OHC for you all (the box has not come yet). I suspect the part # will only get you the OHC (for a SR-equipped Blazer) and the trip computer (which is not the full blown version that the EXT has) will not be included, it will have a seperate part #. I will post pics too.
 
There is a longer console (from the Blazer family) that has a second set of courtesy lights. Anyone know if that would work in the 'non-SR' version of the AV?

--BN
 
Yes, it will. Avoid the console from the Astro/Safari. That one will not work.

You can recover the bezel in headliner material that matches the Av or graphite vinyl that matches. I'm partial to the vinyl as I think it looks more OEM.
