Thank you for asking your question on JustAnswer. The radio and power window share the same accessory delay relay, which is probably having intermittant issues, double check the wiring and the connectors, but most likely the relay is starting to fail.
See system wiring diagrams below.
Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.
is this relay located in fuse pannel under steering colum?
Thank you for asking your question on JustAnswer. Yes that is correct. The relay is located in the CJB (Central Junction Box) or otherwise known as the interior fuse panel. (see diagram below).
Thank you for asking your question on JustAnswer. The instrument cluster also uses the same relay, (see diagram below). Inspect the connectors and the wiring for any corrosion or damage.
The Delayed Accessory Is Inoperative
The delayed accessory relay coil receives power from the battery saver relay through circuit 54 (LG/YE) whenever the ignition is in the RUN or ACCESSORY position. The battery saver relay is integral to the instrument cluster (IC). The IC simultaneously activates the battery saver and the delayed accessory relays by grounding the relay coils when the ignition switch is in the RUN or ACCESSORY position. The IC grounds the delayed accessory relay through circuit 1332 (LB). The delayed accessory relay will remain active for 10 minutes after the ignition is turned OFF, or until a door is opened. When the delayed accessory relay is active, power is sent to the audio system, roof opening panel, power sliding window and power window system.
YesREFER to Section 417-01
to diagnose the battery saver relay. TEST the system for normal operation. NoREPAIR the circuit. TEST the system for normal operation.
Under normal operation, the instrument cluster (IC) grounds the accessory delay relay through circuit 1332 (LB). Power is sent to the LH front window control switch through circuit 400 (LB/BK) from the accessory delay relay. The LH front window control switch is grounded through circuit 57 (BK).
