2006 chevy impala radio & dash lights stay on now when ahut car off, key out and close and lock doors automatically. Never happened before. Help please..


Could be relay contact's stuck closed allowing power to stay on . Or it could be a BCM - body control module problem .

Retained Accessory Power (RAP)
The retained accessory power (RAP) system allows certain vehicle functions to operate for a specific amount of time after the ignition switch is turned OFF. The body control module (BCM) monitors the ignition switch position, battery condition, and each door ajar switch status to determine whether RAP should be initiated or terminated. RAP is controlled with two different methods; serial data and relay control. Some modules receive a RAP message from the BCM over the serial data circuits. Serial data controlled RAP is deactivated as required by their modules RAP power mode operation. Other subsystems are activated directly by the BCM through a RAP relay. Components and systems that are active in RAP are also activated anytime the ignition is any position other than OFF regardless of the door switch signals.

Relay Controlled RAP
The BCM keeps the RAP relay energized during all power modes, except Off-Awake and Crank. The relay is also energized for approximately 10 minutes after shutting the ignition OFF and removing the key, providing no door is opened.
Relay controlled RAP will end when one of the following conditions is met:
• The BCM receives an input from any door ajar or open switch indicating the opening of any door after the ignition key is out of the ignition.
Important: If the BCM is receiving any door ajar or open signal from those switches when the ignition key is turned OFF, RAP will not initiate.
• The BCM internal timer for the RAP expires after approximately 10 minutes.
• The BCM detects a decrease in battery capacity below a prescribed limit.
Systems powered by the RAP relay during the RAP power mode are as follows:
• A/T shift lock control solenoid assembly (w/ floor shifter)
• Power window circuit breaker
• RAP fuse
• Inside rearview mirror (DD6)
• Sunroof (CF5)
Serial Data Controlled RAP
RAP systems controlled by serial data are as follows:
Radio
Radio RAP activation/termination is the same as relay operation with 1 exception; the only door switch that will turn off the radio during RAP is the driver door open switch.
Vehicle Communication Interface Module (VCIM) (Onstar®)
VCIM RAP activation/termination is the same as radio operation with 1 exception; if there is an active call when the ignition key is turned off the VCIM will remain in RAP mode, and keep the radio in RAP mode until the call is terminated.

Do you know what a DTC - diagnostic trouble code is ?
DTC B1475 00: Retained Accessory Power Circuit

How to replace check horn relay for 2000 chevy malibu


The horn micro relay is in underhood fuse box, number 21 in the circle. Your owners manual should have this info. If you don't have an owners manual, you can look at one for free, my.gm.com
It'll ask for year--make model. The relay might not be the problem?

I removed the back seat seat cushion for cleaning and broke the two plastic latches that snaps the seat cushion down in the front. How can I replace those plastic latches on my 2005 Chevy Malibu?


most likely a local upholstery shop will be able to repair, but if you are handy several (black uv resistant) tie raps (cable ties) will do the trick too. Be creative the ties are very strong

Sunroof will not work


Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

The RAP relay is responsible for the radio and windows working after the igntion is turned off.

The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

(1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay(1) Park Lamp Relay
(2) Courtesy Lamp Relay
(3) Retained Accessory Power (RAP) Relay

(10) Door Unlock Relay

2004 chevy malibu 2.2 driving 60 mph shut down


either you have a fuel pump that went out, or your fuel pump relay went. These fuel pumps last around 100,000 miles, so if you're way under that, it's more than likely the relay, if you're close to that, it could be either.

Horn


No the Chevy Malibu is not made by Kia!
I think you mean horn relay
I would try a new relay it is possible that the relay is defective and that's why it was removed
here is how the horn circuit works
The body control module (BCM) controls the horn relay by grounding the control circuit of the horn relay coil. When the horn relay coil is grounded, the horn relay contacts close, applying voltage to the horn via the horn supply voltage circuit.
if the horn relay does not fix your concern you may need to take it to a shop and check for any BCM fault codes
and you are correct having no horn is a SAFETY ISSUE
that car should have NEVER PASSED A SAFETY WITHOUT A HORN
hope this helps good luck and I hope the relay fixs it because a BCM is costly

2005 chevy malibu won't start


You will need to Check the Fuel Pump and Relays, and also Change the Fuel Filter. There is a Fuse Relay Box under the Hood that has the Fuel Pump Relay in it.
