HVAC + actuator + parking lights+abs

[wags]

Hello every one
i am new to the forums and was surprised with all the help and information shared
I hope that you help me on this one
I have a 2003 grand AM GT
First started with problem when changing from hot to cold or opposit was not responding
i found the actuator not responding to the panel switch ,i removed the actuator then used to switch the door manually .
now new issue happening that the HVAC blower is working intermittently on and off,i checked the HVAC fuse looks ok,i replaced it with a new one didn't make a difference
when it happen it is not working at all on any speed so the resistor sounds ok
at a certain point i suspected the control panel board but it looks ok visually,is there a way to test it??
also parking lights some times not working for right and left then if i hit the parking light button 3 or 4 times it start to work for right and left
is this could be related to HVAC issue ??
is there a BCM connector should be checked?
one last thing may be related may be not ,the brakes light are on all the time while oil is good also the abs light os on all the time
I know that i put many questions and information but just wanted to explaine the issue with all details
Thanks a lot for your help

On the blower I would first check the connector on the blower motor, loose/corroded.
Not sure what you mean by "parking light button", the parking lights are controlled by the multi-function switch by twisting the end. If you mean the 4 way flasher they are known to have issues and should be replaced.
Not sure what the brakes lights are on all the time has to with the oil is good?
The ABS light could be caused by a bad wheel sensor or connector.
