2002 Mercury Grand Marquis Question: No heat or defrost in 2002 grand marquis. Thermostat problem?

No heat, Air conditioner is fine, windows wont defrost -
Answer 1
Your thermostat is probably not the problem, unless you have an overheating problem as well. You could have a bad heater control valve since your air conditioning is working fine. -

Thanks, how much would that cost to fix and where are you located? OK thank you -

Proper diagnostics should be administered first, but if it is the heater control valve, the cost: parts, labor, coolant, tax is about $238. We are located in South Sacramento. Off 99/Fruitridge Rd at 5681 Franklin Blvd, Ste C. -
