Thanks KTM
Hi KTM, thanks for your inputs. About your questions:
Have you removed the horn pad on the steering wheel and verified those connections are healthy?
Yes, I removed them and checked them. Those connections go to the break pedal and they are part of Connector C207 (Gray connector). I unplugged it and checked the resistance and turned the steering wheel - everything it is in parameters.
Horn works ok?
Yes it works.
Going back to your A/C, you found a loose connector, as I recall - has the dash been out of that car? Was it swapped in? Does it have an aftermarket stereo? Alarm?
- No, no aftermarket stereo, or Alarm. I am pretty sure the problem was the speedometer, it was not working. I have the impression that the previous owner tried to fix it and removed the dash and did not take the time to put all the connectors back in place. The gentleman who fixed the speedometer, in addition fixed the high beams and few other things that were disconnected. I connected the sensor and removed the E3 problem.
About the AC. I bough R12 and I might get it before the weekend. I will go with a friend that has a way to check the pressure and hoses for R12 and in case it needs refrigerant we will fill it.
Can you see the multi-wire connector for the ignition on the side of the steering column? Is it opening up when you turn the key?
- I am not sure, but wasn't that the connector that I was previously checking - the one that I was originally confused with the C207 (beginning of the post).
I'm not saying those are/aren't directly related, but you seem to have uncommon root causes so far, so it might help to not limit yourself to otherwise trusted troubleshooting procedures, and look for -anything- that might be out of place, etc.
- I agree. the previous owner was not using the car; but when when he was fixing something, I got the impression that he started testing and just left unplug multiple things.
Is the cruise control cable connected at the throttle body?
It is, I already checked that portion.
KTM, I think in this moment there is no reading for the "Modulating Valve", And I need to fix that problem before I move to the next step. But before I remove the front cover fender - I am wondering if there is something else to check. In my previous comment there is a link to a thread, and they are talking about connector C109; located in the area behind the passenger headlight..... I don't see it in the manual or looking around that area. Tomorrow, I will remove the cover fender and search for the "Modulating valve"
Thanks KTM
