Why is there no heat in my Ford Escort?

It sounds like the issue with the lack of heat in your Ford Escort could be related to the heater control valve. This valve controls the flow of coolant to the heater core, and if it’s stuck shut, it can prevent the heat from working properly. It’s also mentioned that if the heater core was the issue, it would likely be leaking or blocked, causing the car to overheat. Additionally, there’s a possibility of an electrical problem or a vacuum concern related to the heater control door in the heater box. It’s suggested to check the vacuum lines on the back of the heater controls, as they could be the cause of the issue. If you’ve recently had an aftermarket CD player installed, it’s also recommended to check the fuses and vacuum lines on the back of the heater controls, as they could have been affected during the installation process.
Possible Causes of No Heat in Ford Escort:
– The heater control valve may be stuck shut, preventing the flow of coolant to the heater core.
– Electrical or vacuum concerns related to the heater control door in the heater box.
– Issues with the vacuum lines on the back of the heater controls, possibly affected during an aftermarket CD player installation.
It’s important to address these potential causes to diagnose and resolve the issue with the heat in your Ford Escort.
