2008 Trailblazer HVAC not working Viper 4706v

Somebody on here must not, because thats where I found a referance to the brown wire being HVAC.

Its whatever though, live and learn. I appreciate all the information here. Very helpful.

Now Ive got another issue,the remote start will shut off after slighlty more than 2 minutes. My flashes from my led diagnostics go 11-11-11-5-11-5-11-11. Not really sure how to interprit that. This dod not happen prior to hooking up the RED / black

I think i understand the flashes as a history of why the remote start shut down, so my current shutdown status would be 11. 11 Being Wait-to-start input timed out, idk why I would be getting that error??

Any insight on this issue? Just not sure how it went from working fine. to doing this overnight.

First, I would double check all the connectors to ensure they were completely seated. Next, I would make sure my Viper to Chassis Ground connection was perfect. Use a soldered-on terminal ring and fasten to a solid, paint and rust free metal frame area. Does your 2008 Blazer have "one touch starting"? That is where you can quickly turn the key to START and release it back to RUN and the ECM will control the starter crank time and start the engine. If yes, are you running the Viper in Tach or Virtual Tach Mode? If yes, try switching over to Engine Checking = Fixed and go with a one second crank time. See if that helps.Soldering is fun!

Checked my connections, they are solid. I am currently running off virtual tach. Im not sure how to change cranking time?

found it in my instruction sheet, i set engine checking to off. same thing. Shuts off around 10 or 11 minutes left . Timer is set at 12 minutes

I should also note. This is a factory refurb unit.
