Service Procedure
1. Inspect the block heater power cable inline connector for signs of water intrusion. The connector is located directly behind the right side bumper and can be accessed from under the vehicle. (Figure 1)
Figure 1
2. Is there evidence of water inside the connector?
(1). Yes – proceed to Step 3.
(2). No – this article does not apply. Refer to Workshop Manual (WSM), Section 303-03C for normal diagnostics.
3. Remove the right front fender splash shield. Refer to WSM, Section 501-02.
4. Replace the block heater power cable. Inspect the new block heater power cable for electrical grease within the inline connector. Is there electrical grease present? (Figures 2 – 3)
(1). Yes – proceed to Step 6.
(2). No – proceed to Step 5.
