Instructions for carrying out Workshop Campaign WKE0, Retrofitting Relay for Activating Control Unit for Air-Conditioning Blower. Optimized control units for the air-conditioning blower that are needed as part of campaign AKA7 are currently not available yet in the quantity required for retrofitting all affected vehicles immediately. To remedy this situation immediately, an interim measure is required. As part of the interim measure, the previously installed blower regulator must be additionally sealed using a sealing cord, thereby preventing further moisture from seeping in. An additional relay will also be installed in the electric wire harness for the blower regulator.
