Public Service Announcement: Think and do research first! Don't be like Tygaboy!Let's forgo further attempts at humor and get right to it:
My car does come up to temp, the regular ol' thermostat set up works fine, I don't need to get all fancy with ECU controlled water pumps and fans - though I may choose to do that later, just 'cuz.
Turns out
SpeedHut temp sensors use a different ohm range than that of GM sensors - even though they use the same f-ing wiring connectors. Totally my fault/lack of knowledge, but still...
Maybe some of you already knew about the specific gauge = specific sensor. If you did, thanks for nothing in terms of letting me know!
I stumbled on the following charts about 5 minutes before pulling the entire drive train and going all "high tech solution" to try and resolve my perceived issue. A quick comparo of these charts to the temp behavior I was seeing and I was sure this was it.
Today I installed the correct sensor, fired up the beast and sure enough, it's all good.
It comes up to temp, the fans kick on as expected, etc., etc.
Yep, it's another case of "problem solved for $18...".
Anyway, that's a long way around to your lesson for today:
"Determine root cause to be sure you're address the issue, not treating a symptom".
The best news is that this means the vents do, in fact, work just fine! At least as far as I've pushed the car to date, which isn't much. Who wants to come along for a "stress test" drive?
In all seriousness, maybe this lesson helps someone else avoid the same thing.
