I still have one of my erector sets from the 50’s. It’s the one with the A.C. motor.
@old_mopar_guy Is the motor clear with a yellow sticker on it and little knurled finger bolts to hold the wires? And the pulley on the motor would be like a small groove to drive a string? My set couldn’t be much older than 1970 or so… .
Motor is blue and gray. Power cord runs directly into the motor. Yes, grooved pulley.
Well…the thing is…even with all that caked on corrosion (on both the PCM housing and it’s circuit board), disintegrated IC leads and subsequent limp mode, my cars condition still doesn’t fit the necessary qualifications for a PCM replacement (in terms of the recall procedure)!! The only DTC mine throws is U0107, lost communication with TAC module. DTC P0606 (ECM internal processor malfunction) MUST BE PRESENT to get the ECM replaced under recall. This is the ONLY way techs are instructed to replace the PCM. It even says that all PCMs that are replaced must be sent in for inspection to make sure they contain that DTC, so if a dealership replaced one that didn’t throw that code I’m assuming they’d be hearing from corporate! The recall procedure says that if a vehicle lacks the P0606 DTC then the tech is instructed to wipe the corrosion off the outside of the module (by spraying a towel with cleaner & scrubbing the module with the towel) then tape the (cheap ass) “cover” on & bolt the ECM/PCM back in the car.
So my point is: the recall procedure is completely inadequate for remedying the corrosion issue!! It’s like expecting a laptop to show you a message saying “there’s a problem with your motherboard” if you spill something on it when in reality there could be any number of errors in the laptop, depending on which components/parts of the circuit were affected etc.
My cars condition (being undriveable) is a direct result of the PCM becoming corroded 100%! In one of my pics you can even see that the edge of the carpet (which was in contact with the PCM) had corrosion on it. I’ve gone to salvage yards around my area and the PCMs I’ve found have ALL had corrosion in the same spot!! Even looking online at PCMs I’ve noticed corrosion on some! It’d be hard to tell if I didn’t already know where to look but, well I’ll add a screenshot example to show you what I mean…
It’s been awhile since I wrote this. I ended up getting side tracked when looking for an example of a PCM online with corrosion. I just came back here after checking emails and finding one from this forum.
