Supposedly they are better now and are suppose to be improved, but my problem was how did I know I would be getting the ''B'' version since it still has the same number stamped on it. Since I was quite satisfied with the performance of these, I stayed with these. I only have 60 left and will be ordering an other batch soon, hopefully the Canadian dollar will rise a bit since I order these from a place in California.

Along the same lines...................the P-R-N-D-L LED on my 03 Silverado is dead. Any way to replace that or does the whole board need to be replaced?

There is no LED for the PRND321 display in an 03 just started in 06, it has an electroluminescent display. You will need to re-flow solder of the seven 510 ohm resistors at the top left of the speedometer stepper motor and the one 560 ohm just outside the red circle. You may need to add a little bit of solder to accomplish this properly.

Oh really ? Cold solder joints? Age? Reason I say that is my 04 Vettes electronic climate control display started getting dim and then almost went completely out...fix was to remove board, re-flow solder along each side of the 8 resistors and it was good as new.

I'm guessing it;s the same thing for my trucks PRND321 as well ?

Yup, these resistors are to close to the background speedometer bulb which gets very hot at times causing these to crack and eventually fail.

 

This is one of the reasons I replace all bulbs with LEDs, it drops consumption of cluster by 10 watts

You're welcome, here to help and I have no secrets to keep.....keep your iron around 750°F if you don't want to lift the foil off the board.

Re-flow of solder on the 8 resistors was a success...I did run into a slight problem when 2 of the stepper motor shafts pulled out while removing indicator needles but believe it on not, I un-soldered the 2, split the case open, re inserted the shafts in the gears, lined up the stop indicator pin inside and reassembled . re soldered back on to the board.............EVERYTHING WORKS !


I do think that , since all of the stepper motor sweeps had a bit of scratchiness to them I'll order 6 new ones and replace them.


Thanks again for all of your help !

On my 99 silverado I just purchased yeseterday the Guage cluster was working great but today the rpm Guage is not working amd odometer is blank amd message centre is not lite up ..possibly spedometor is also not working.

I have to chime in and say thank you guys. My PRND has been out for about four years. Figured it would need the cluster replaced, however I did replace a few stepper motors prior to the display quitting. I shrugged it off but the wife reminds me of it to this day. I will have to convert to LEDs replace the tach motor and reflow the resistors. Wish me luck!

Yours OEM Switec / Juken Motors? All mine are white from switec. I just redid a cluster from myairbags.com and they had black motors in them.

Black motors had failed or you replaced them anyway? I've never had a black motor fail in 6 years.... I'm kinda wondering if that cluster didn't have a different problem.

Just don't overheat anything on these boards.

Mine were all white, it's been about six years since I did it. My tach is lazy below 1K RPMs, so I figured I'd replace it while I'm there. Just another project to add to the list.

So if I was going to buy a single stepper, I see on Amazon the white 5th generation and a six pack of the black ones? What's the final verdict on them? Thanks again!

I've never had a problem with the black ones in 6 years so I never went back to the white ones. Apparently they are now at the sixth generation so they probably have it right by now with the white ones. Problem is you don't know which generation you're getting unless specified because they all look exactly the same.

      Lets Talk Z60 Suspension

      By ryan35205 · Posted

      Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.

      Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.

      I just spent the last 45K miles doing samples every oil change over more than a full year to get the data for seasons and break-in to broke in.    I found the same thing to be true. Something was always teetering on done or had stepped off the cliff long before the OLM was DOA. In fact, I found about a thousand mile difference between summer and winter. That is during the winter half the OLM was STILL too long. Even the severe schedule was to long in the winter.   Now having done the work I can say I was NOT DISAPOINTED. I saw nothing I didn't already know. Nothing my father hadn't already demonstrated in his 2K OCI's pushing dated iron on dated oils and weak filters to mileages well beyond 300K.   Building on his work through use of Lab testing it wasn't hard to find the correlation between 'sight/feel/odor, the things dad relied on, and test results. Use of current viscosity stable chemistries & filters has pushed that marker for my motors out to 3K summer, 4K winter.    So the early lies were 3K on conventional oil and the lie upon the lie was 7K+. turns out to be off by a factor of two.    So... it is true that modern chemistry has doubled the useful oil life. But the base milage that came from was off by double. It's how good lies work. Partly true, sometimes mostly true so that your meter isn't set off. It also means that non-shear-stable shelf oils are only now as good as the old oils were in their best case scenario.    So the question now is how do we improve on that? Thus the question into cleanliness among the other items listed in the post quoted below.    If this bores you, feel free not to participate.

      Is it though?  Like LTZ, not a high take rate.  Current Sierra has AT4, Denali and Elevation as its main bread winners.  Each trim accounting for 25-35% of sales for Sierra.  SLT makes up about 10-15% at best.        Like others have predicted here for GMC, it will be:   - Pro (equal to WT Chevy)   - Elevation (replaces SLE and SLT)   - AT4 (and X)   - Denali (and Ultimate).
