    Per the video on this problem I recalculated the system but it did not correct the problem. My HVAC still will blow cold then hot then back to cold sometime later. I've turned it off and on numerous times, turned the truck off then back on with no help. What next?

    2005 Tahoe

    Within the last 6 months I have had periodic starting problem. Just randomly have to keep turning the key till it starts. New battery, tested starter (good). When dead, lights come on but engine is totally quiet almost like battery is disconnected. Normally takes 25-30 times and then it starts. WTF?

    HVAC problem

    A/C blows cold then hot then cold. Was told there was a simple sequence of action that will reset system. ie: push auto twice, wait 30seconds,turn key on, etc. 2005 Tahoe with digital unit.
