Air re-circ at start-up

[jeffb]

Hi All,
I've a 2002 LC that I've owned for 7 years now. Greatest truck EVER. Ive a remote start installed that works great. Of late if the temp is below 40 degrees when I start my truck the the air re-circ switches to open bringing in cool outside air. This makes it difficult for the truck to heat up inside. I thought it may have something to do with the remote start but the same event happens if I start er up manually. This does not happen at all with slightly warmer temps. It used to never happen even at temps around 20.
Any thoughts on why this may be occurring? Ive been reading some threads on the air cabin filters. Possibly related? Havent inspected if they are even present yet. Thanks

Defrost uses the fresh air along with the A/C to get the moisture out. My Tahoe used to do the same thing.

What remote start system do you use?
