2004 Chevrolet Avalanche 1500 Q&A
2004 Chevrolet Avalanche 1500 Question: heater not working.
there is a leak if you have to add. have a shop pressure check it for you. Roy - mastertech6371
I agree with Roy. You have coolant going somewhere. If the coolant level drops it creates an air pocket and can stop circulating to the heater core, causing the loss of heat. We would be happy to look at it for you. www.fenskiauto.com Matt - fenskiauto
I have changed the resistor twice in a month. the blower & motor is new and still works. What could be causing this to happen & how can I fix it.
i have abs lite and brake lite on dash, code reader says 0141 but mechanic says its my electronic brake control module which is up to $1000. to fix. and when i search i get o2 sensor for code 0141...
