How to Remove the Heater in a Classic Focus?

Classic Focus heater removal method is: 1. Remove the glove box on the passenger side; 2. Remove the internal and external circulation ducts inside; 3. Go to the driver's side accelerator pedal, unscrew the mixing head downward, and push it toward the passenger side. The heater is a combined unit consisting of a fan, motor, and air heater, suitable for various types of workshops. When the air does not contain dust or flammable/explosive gases, it can be used for circulating air heating. Taking the 2021 Focus as an example, its body dimensions are: length 4647mm, width 1810mm, height 1468mm, wheelbase 2705mm, fuel tank capacity 53 liters, and trunk capacity 511 liters.

Last year I disassembled the heater blower in my classic Ford Focus, and the process was a bit more complicated than expected but still manageable. First, disconnect the negative terminal of the car battery to avoid electric shock risks. Then, locate the panel under the center console from the passenger side and loosen the screws with a Phillips screwdriver—there are about two or three hidden in discreet spots. Carefully pull out the panel without forcing it to prevent plastic parts from breaking. Inside, you’ll find the heater blower unit. Gently unplug the wire connectors, noting their positions to avoid confusion during reassembly. The bolts securing the heater are usually on the sides or bottom; once loosened, you can slowly remove it. Take your time with the whole process—it should take around half an hour. Before starting, clear any clutter in the car to avoid obstructions. If the fan is dirty, wiping off the dust while you’re at it can improve efficiency. Remember to handle all parts gently throughout—unlike my first rushed attempt where I snapped a wire. After the repair, the heating performance felt much better!

Removing the heater blower is a practical DIY task. First, disconnect the battery to ensure safety. Then focus on the area below the dashboard; the Focus' heater blower is usually on the passenger side. Use a screwdriver to remove the panel screws—most cars have four or five. After removing the panel, you'll see the heater blower unit. Unplug the electrical connector and any hose connections. Next, loosen the mounting bolts, but don't over-tighten to avoid stripping. Be careful not to bump surrounding sensors when removing the heater blower. The tools needed are simple: just a screwdriver and gloves. If you're just cleaning the fan, it's easy to remove and brush off the dust; replacing parts might take more time. I recommend beginners take photos with their phones to note the positions for easier reassembly. The process isn't difficult but requires patience. Once removed, the heating system is much easier to maintain.

I tried removing the heater blower on a Focus, and the basic steps are as follows. First, disconnect the power to prevent short circuits. Then, remove the dashboard panel on the passenger side and locate the screws to unscrew them. Pull out the panel to reveal the heater blower, disconnect the wiring harness, and loosen the bolts to remove it. The process takes about 15-20 minutes, and all you need is a screwdriver. The tricky part is the tight space, requiring some dexterity. Safety is the top priority throughout the process—don’t overlook details like noting the orientation of the connectors. After the repair, the airflow noticeably improved.
