Rear Heater blows cold air.It blows hot air once in a blue moon.
What is your question?
Hi,my rear heater is blowing cold air.I took it to a shop,they told me it's the heater core,so i change it,a $ 300 job.
But it's still not working all the time.They told me to press on the gas pedal to send hot coolant to the back for it to work but still it's not working.Does anyone know what's wrong with it?
Winter is very close now and i have small kids.i would really appreciate if someone could help.
Thanks

RepairPal Certified shops can diagnose and repair your 2004 Chevrolet Suburban 2500. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
So I noticed that as well with my truck. So If you put the back heater all the way to 80 temp and on feet only while your truck is warming up. it will start the warm up processes in the back. Once your truck is warmed up, you then can turn the switch over to heat the head (Not Feet and Head) just Head. and you will notice it to blow hot air. you then can adjust the heat temp and it will continue to blow hot air. Hope this works for you and hope it makes sense for you as well. Good Luck!
