Heater actuator BEHR Citroën Peugeot EAD515 P2861001U b 44 647947

Description

BEHR heater servo motor for CITROEN C5 X7 and PEUGEOT 407 facelift cars

Part description

Used BEHR heating servo motor intended for controlling dampers in the heating/air conditioning system. If you are solving a problem with air routing, temperature changes, or non-functioning or irregular flap control, the servo motor is a frequently searched part – and in practice it is most often found by the codes listed on the label.

The advantage is a quick replacement without the need to find the entire heating set – if you choose correctly according to the part number, you will get a functional replacement with the corresponding connector and attachment.

Installation recommendations

Generally/typically for heater servomotors it is an electric damper control in the HVAC unit. The exact procedure may vary depending on the specific design of the car and the approach to the part.

1) Before assembly

• Compare with the old part: codes (EAD515 / P2861001U / 647947), body shape, mount, connector (number of pins and locking).
• Check the condition of the connector and wiring in the car (oxidation, loose pins, damaged insulation).
• On the used part, visually check that the brackets are not cracked and that the shaft/driver is not damaged.

2) Necessary tools and materials

• Basic set of screwdrivers and bits (according to the type of screws in the interior)
• Ratchet with attachments (according to access)
• Plastic pry bar for panel removal
• Flashlight
• Electrical contact cleaner (optional)

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery (to protect the electrics and eliminate errors when disconnecting the connectors).
2. Give access to the servo motor by removing the necessary covers/trims (extent depends on the car design).
3. Take a photo of the original condition: cable routing, connector position and part seating for easier reassembly.
4. Disconnect the electrical connector – do not pull on the cables, release the connector lock.
5. Unscrew the fixing screws and carefully remove the servomotor.
6. Check the follower/damper connection: it must not be cracked, squeezed or blocked.
7. Before fitting the new piece, gently clean the contact surfaces and possibly the contacts of the connector.
8. Place the servo motor in the correct position so that it sits on the flapper driver without force (if it does not fit smoothly, it is usually not in the right position).
9. Screw the servo motor back in and check that it is firmly seated.
10. Connect the connector and verify that the connector fuse is properly engaged.
11. Reinstall the removed covers/trims.
12. Connect the battery, turn on the ignition and perform the functional verification (see below).

• 4) Post-assembly checks and test drive/function verification

  • Check temperature change and air flow direction – response should be smooth and without irregular dropouts.
  • Watch for unusual noises (clicking/skipping) which often indicate a problem with the flapper or follower engagement.
  • If diagnostics are available, review any stored HVAC errors and delete them after repair.

  5) The most common assembly mistakes + how to avoid them

  • Part exchange by similarity → always compare by codes and connector (EAD515 / P2861001U / 647947).
  • Torn handles or cracked holders during assembly “by force” → the part must fit naturally, without prying.
  • Not addressing the cause of the damper sticking → if the damper is difficult to operate, the servo motor may go away again.
  • Damage to the connector when disconnecting → release the fuse, do not pull on the cable.

  Reasons why the part is damaged

  • Wear of the gears of the servomotor (long-term operation, frequent adjustment of flaps).
  • Stuttering or damper resistance in heating/air conditioning – the servomotor is then overloaded.
  • Moisture and oxidation of contacts in the connector or around the HVAC unit.
  • Voltage fluctuations or an electrical fault in the installation (bad contact, transition resistors).
  • Mechanical damage during previous disassembly (cracked handles, damaged driver).
