Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Have you checked the coolant level?
Hello! Yes, I am here. Would it be easier to speak on the phone?
No problem. I will be happy to help anyway I can.
First, you are going to need to check the coolant level and check for any leaks. If there are any leaks at all, this can cause a no heat situation.
If the cooling system has a small leak, the coolant gets replaced by air and the cooling system will eventually develope a big air pocket which will cause a no heat situation.
No, you need to just wait for me to type the answer. PLEASE BE PATIENT
Second, if there is no coolant leaks and the cooling system is full, then we check the thermostat operation as it may be a stuck thermostat. It can stick opened preventing the engine from heating up.
If the engine is fully heated up, then we check the heater hoses going to the heater core. If one is hot and the other is cold, then it is possible that the heater core is plugged up. We then would try to flush out the heater core or possible replace the heater core is that does not work.
Now, if both of the heater hoses are nice and hot but there is still not heat coming out of the vents, then it is possible that the blend air door or the blend air door motor inside the dash has gone bad causing this condition. It may not be opening enough to let heat through the vents.
Does that make sense?
