blows no heat
My 2012 dodge ram 1500 is a base model truck.
The dealer ship has replaced my thermostat, cold
hot dial, and my heating core. In cold weather(-25C
or colder) it blows no heat. I turn the dial to front
instead of dash and it blows snow out on high
After all that work, the dealer didn't confirm the repairs worked? Since they replaced the heater core, it should be safe to assume they ensured the blend door at least is working, but it sure reads like you have a problem with a mode door not working, maybe the recirc door? Did they touch the cabin filter at all?
I think maybe try a heater control calibration. Then all the doors and the heat will work together. Cause I know that duramax chevy and gmc if the batterys die the heat needs a recalibrate for a reason
My 2012 ram 1500 heat stoped working did this before and all I had to do was push the controls and it worked but I can’t remember what I did anyone know, it only happens when it gets real cold
Blower on low; hold air recirculation button in for 10 seconds, release; hold it in again until the recirc light flashes (about 10-15 seconds); release. It resets the stupid computer that has glitched. Found answer on another forum but don't have it here to post link.
Bobbie you're right! I tried the recirculate reset and it worked.
It worked for me also! Thank you
Thank you Bobbie your a lifesaver!!!! Froze my ass off all the way home from work about 30 miles at -6 degrees and was just about to order a thermostat. Luckily I decided to do a little research and found this forum. Went out held the button til it flashed and lol like magic hot air.
I just tryed but not resetting the controls are dead but blower works not recycling ac or heated mirrors
My heater is not blowing hot air.
Bobbie for Prime Minister... It works for my dodge ram 1500 4.7l. Thanks
Bobbie, that worked. Appreciated, -2 this morning
I'm warm again, thanks for the hack!
Nice...car gurus..it worked
Yes Bobbie is right!!!! My heat start working instantly thank u I have a bighorn ram 2013 my light didn’t flash but u felt the heat instantly after the first ten seconds of holding the button
Kk did reset thing. All lights did as you said. I had my blower control out of heater box as it hit broken and I m j b big the pcs back together. The control got extremely hot extremely quickly. Is this normal
Bobbie you just saved me a pile of cash bud! Thanks for posting
What happens if the light doesn’t stop flashing
Thanks Bobbie -25 in Saskatoon Canada froze my butt off till I got home and saw your post worked like a damn. Cheers.
What do you do if you don’t have a recirc button. I have a dial and sync/ac buttons only
Your recirc button is on the left knob. The little car with an arrow in the shape of a “C”.
Winnipeg currently -41c just happened to me, luckily tried the recirculation trick and it worked!!! Thanks guys
Thanks Bobby. It is minus 42 in red deer and it worked just as you said it would. You just saved me a pile of money. Love coming to these forums to find answers from knowledgeable people like yourself
AMEN BOBBY!!!!! Darn computers. Taber
I must be doing something wrong in the reset. truck on or off? how long between the 10 sec and the 15 sec holding. can't get it to flash
didnt have any results then I turned off the blower button then pushed on the button and turned on the blower and it worked Warm Air!!!
Hey Bobbie, right on my man your little trick worked for me and its -35 celcius in Ottawa
When I press the recirculation button, it immediately flashes 3 times. If I hold it in, nothing happens. I still don't have any heat and it's -30C in Kenora, Ontario!
