2006 express van heater won't work.

Asked by Feb 29, 2016 at 03:14 PM about the 2006 Chevrolet Express

Question type: Maintenance & Repair

Heater was working when got to work. Got in 10 hrs. Later and it didn't do
anything. Checked all related fuses according to the owners manual.
Replaced the heater motor resister, heater blower motor, climate control
switch assembly in the dashboard .... NOTHING CHANGED...
The ABS light came on when this happened also....am told that has nothing to
do with the heater?... I have asked several friends who own the same van...
They have had problems also... but they just spent 800 to get it fixed and
moved on. The shop won't help me unless I'm paying.
Any suggestions of what to for check next?

I finally got the time to do some extensive research for a great tech guy..put it into a very inexpensive and very reliable shop to not only have it diagnosed but also repaired...he is licensed,,bonded and is a guy who grew up in the same town and looks out for everyone.... It was the ignition switch..and a blown fuse under the hood. When they replaced it the heater and ac worked just fine.. And the ABS light on instrument panel went out. Cost was 226.00... My problems may vary from others but this just gives you an idea. Also for FYI.. The tech also said that if the van every has a problem with starting or dies all of a sudden when driving it is most likely the ignition switch..and or an ignition control module. They can be checked. So I advise to do diligent research on the person or persons who want to diagnose your problems because it can cost a lot.. It may seem like a waste of good time but the results may not seem so great when they drain your bank account just to say.. We are trying.. Sooo Good luck out there to all..!! ✌️

Above suggestion was very helpful. I replaced the resistor, but that was not the problem. I could not believe it but the cause for the ABS light coming on and heater fan not coming on was a bad ignition switch. $50 after market ignition switch fixed the problem. I did not have a fuse burned out as Chuck suggested above. Never would have suspected the ignition switch because I never had a problem starting the van. To fix , just have to take the lower cover off around the ignition switch, pull out the switch, unplug the plug and put the new switch in. If the "Security" light comes on, just put the ignition switch out again rotate white ignition switch gear two notches to the left and replace. Easy fix for a big headache. Thank you Chuck0317
