No warning lights

[Thetimadator]

When I cycle the key on to start the car, none of the warning lights come on on the dash. It is a 1986 Olds Cutlass salon. I've also noticed that the TCC does not lock up correctly. Every now and then it'll momentarily lock up after 45 mph but within 3 seconds it unlocks and then that's it. At about 70 mph it'll lock up for a little bit longer duration of time and then cycles. I'm curious to see if anybody else has had the same issue with the warning lights coming on in May of had a ECM failure or something like that.

Have you tried seeing your codes? Locate your OBD connector, and grab some wire or a paperclip, to see if anything flashes.

Yep and nothing happens(check engine light does not flash or come on at all. I can tell the engine runs different as grounding A to B goes back to base timing and as far as the TCC it will lock up and stay locked as long as I ground A to F. The car has a bad rear main seal leaking and the oil level got low enough that it dropped to near 0 when i came to a stop the other day and but the oil light never came on either. I don't know if this is a two part problem or one problem causing multiple symptoms. If the TCC lock up issue is in correlation to the warning lights not functioning. Do the warning lights pass through a lighting control module or is it directly from the ecm? I'm not as worried about the warning lights as much as the TCC. The TCC does have a new solenoid, 4th gear pressure switch( a N/O switch from Napa, 2 to 8 psi closed) but I have no idea where the actual vacuum switch is. I did find a couple vacuum lines the were bad so I replaced and bunch of those. It had a vac leak at the base of the carb and fixed that also.

You can wire a switch to the TCC I do know that, but one of the other members will need to share how because I'm still learning myself.

That said regardless if there is a lighting control module, no matter if it controls the functionality of the bulbs- it wouldn't be the cause with the converter clutch I'm pretty sure. Your ECM doesn't seem to be working as it should.
