FIGURE 1 - ELC System Check Chart:
Some early production 1985 Devilles and Fleetwoods may experience an inoperative Electronic Level Control (ELC) system. This condition may be the result of a blown ELC fuse. To correct this condition, the following procedure should be followed:
1. If the vehicle was built before Broadcast Number 215122, replace the height sensor with P/N 22048625. Follow installation and adjustment procedures in Section 3D of the 1985 FWD Deville and Fleetwood Service Manual.
2. Replace the fuse and perform the ELC system performance check (see Figure 1).
3. If the fuse blows a second time, replace the compressor (P/N 22020538).
