Default Electrical Gremlins Help

I have a 2002 coupe with 97,000 mi. Car is stock with no issues when the car was purchased 2 yrs ago, but suddenly all kinds of electrical issues.

The ABS/Active handling light is on always (the dash) eventhough the module has been replaced and tested as good. Now I get no comm with the HVAC.Climate control now not functioning. All the grounds where recently checked and cleaned, including the ignition switch.

Now I have rapidly blinking dash lights and both turn signal indicators illuminated. The blinking stops when the headlights turn on.Battery is new and charged. I beleive is it some wiring/ground issue (common to ebcm/hvac) but do not know where to start.

Codes are as follows:

P0135C
P0155C
P1571
P1689
TCS NO COMM
B0432 H C
HVAC NO COMM
SDM U1040 HC
LDCM U1016H

Any ideas or thoughts would be greatly appreciated.

Thanks Jeff

Have you tried wiggling the accordion connecter between the door and the body of the car? You might need to fix a loose connection.

yes ok just tried that on both doors. Same issues but the rapidly blinking dash lights seem now more intermittent. So strange.

Thanks

Try the headlight switch connector under the steering wheel. Common issue.
