Campaign No. 2004070010, October 2004
Revised November 2005
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT:
MODELS 2151220, MODEL YEARS 2000 THROUGH 2001
INSTALLATION OF BLOWER MOTOR WIRING HARNESS
This revised Recall Campaign bulletin 2004070010 supersedes previously issued Recall Campaign bulletin 2004070010 released in October 2004. It contains new and updated Special Tools information and in Procedure B, steps 4 thru 6. Please destroy all previous Recall Campaign bulletin versions.
This Recall Campaign has been initiated because DCAG has determined that on the affected vehicles (see VIN range below), due to a production deficiency occurring during the production process of the blower motor fuse holder, the size of the electric conductor on the blower motor fuse holder may be below appropriate tolerances. Consequently, the electric conductor of the blower motor fuse holder may dissipate more heat than the plastic fuse holder was designed to withstand, which could result in overheating of the blower motor fuse holder and disabling of the blower motor and the ability to defrost or defog the windshield in cold or hot and humid weather conditions. Depending on the occurrence and weather situation, driver visibility could be reduced, which could result in a crash.
Please review the Effective Serial Number Chart.
Included is a sample copy of a letter which owners of the affected vehicles will receive.
Prior to performing this Recall Campaign:
^ Please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.
^ Please review the entire Recall Campaign bulletin.
Approximately 54,438 vehicles are affected.
Effective Serial Number Range
Note:
Every vehicle in the VIN range may not be included in the campaign. VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. VMI always overrides the bulletin in reference to a specific vehicle's inclusion in a particular campaign. Please also note that Recalls and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.
Procedure:
A. PRELIMINARY WORK
1. Disconnect battery ground cable WIS: AR54.10-P-00031.
Caution!
Do not install quiescent current retention unit.
2. Remove right front floor covering WIS: AR68.20-P-2070M.
Note:
Only remove as far as necessary until the foot support is accessible.
3. Remove right front foot support.
4. Lift up right front SAM (WIS: AR54.21-P-1261I) to gain access to harness opening in bulkhead.
Note:
^ Do not completely remove right front SAM.
^ If necessary, disconnect wire harness connectors from ME-SFI control module.
B. INSTALLATION OF BLOWER MOTOR WIRING HARNESS
1. Route new interior blower motor wiring harness (1 Figure 2) with ring connector from the right fuse box (Fill Figure 3) into the right front footwell.
Note:
A wire puller/"snake" (shop made tool: e.g., mechanic's wire etc.) may be used to aid in routing the new harness into footwell area through the bulkhead.
2. Route new interior blower motor wiring harness (1, Figure 2) along existing cables to the cable connector and fuse box terminal 30 (X4110) and secure with cable ties.
3. Connect ring connector to designated M8 screw connection and torque M8 nut (arrow, Figure 2) to 9 Nm. (+/- 1 Nm).
4. Remove brown fuse holder (fuse 35, Figure 4) with 40A fuse from the right fuse box (Fill, Figure 3).
5. Unpin wire connector (with r/y wire, Figure 4) from brown fuse holder (35):
^ Remove fuse from fuse holder (35).
^ Unclip two outer locking tabs (A, Figure 4) furthest from the hinge (B) then partially pry open cover.
^ Unclip two outer locking tabs (C, Figure 4) closest to the hinge (B) then fully open cover to expose wire connectors.
^ Push the wire connector (with r/y wire) out from fuse side of fuse holder using special tools: Blade Handle W220 589 01 99 50 with blade W220 589 01 99 61 (Also, see the "note" on concerning additional Special Tool information).
Note:
^ The fuse holder (35) and fuse can be discarded.
^ r/y designates red/yellow wire.
6. Install unpinned wire connector (with r/y wire, Figure 5) into new harness connector (A):
^ Insert the unpinned wire connector (with r/y wire, Figure 5) into position 1 of the new harness connector (A).
^ Secure wire connector (with r/y wire) into position by locking closed the harness connector cover (arrow).
7. Connect the new harness connector (arrow, Figure 6) to the harness connector on the new blower motor harness wire (1) and place coupled connector (X64/1) below right front SAM in the right fuse box (F1/1).
8. Install new maxi fuse holder (5, Figure 7) into grommet breakthrough (arrow) in right fuse box (F1/1).
9. Route interior blower motor harness below right front SAM in right fuse box (F1/1).
10. Reinstall right front SAM, reconnect wire harnesses to ME-SFI control module (if removed in step 4, subject A) and reassemble interior of vehicle in reverse order.
11. Reconnect battery ground cable WIS: AR54.10-P-00031.
12. Read fault memory and erase using Star Diagnosis.
13. Check operation of interior blower motor.
14. Affix fuse/relay label over area of fuse chart identifying location of fuse/relays in right front fuse and relay box (fuses 28-49).
Note:
Fuse and relay chart is located in trunk under lug wrench (in tool kit).
15. Reinstall remaining parts in reverse order.
Special Tools
Note:
1) Both tools are contained within kit W220 589 01 99 00 and W220 589 02 99 00, previously released automatically to all MB dealers.
2) For new purchase, Special Tool Number: W220 589 01 99 61 has been superseded to a newer version blade, Special Tool Number: W000 589 10 9930. This newer version blade can be used to perform the same function as W220 589 01 99 61 described in this bulletin.
