AC Heater Climate Control Module For Chevy GMC 03-07 – Improved Design, 599-009 By Geartronics

Is your 2003-2007 Chevy or GMC truck blowing hot air when you want cold, or just ignoring your temperature settings entirely?

The climate control module might be the culprit.

This replacement from Geartronics is an improved design over the original, so hopefully it’ll last longer and keep your cab comfortable.

It’s a direct bolt-in and plug-in replacement—no cutting wires or drilling holes.

Just remove the old one and pop this one in.

It works with the automatic climate control systems in these trucks and cross-references with a ton of OEM numbers like 10367041, 10399657, and 15077479.

It’s got two plugs—one 24-pin and one 12-pin—so make sure that matches your setup.

The module itself is black plastic, nothing fancy, but it does its job.

If you’re tired of sweating or freezing because your HVAC has a mind of its own, this is the fix.

Geartronics builds these to last, and it’s way cheaper than a dealer trip.
