Default Check engine light - codes inside

Car usually never gives me problems but last couple weeks the TCS and ABS infamous symbols. They've come up intermittently since 2016 when i got the car, but they've been gone for several years and rarely pop up until now. Check engine light also popped up today and my HVAC display is gone dark.

Car was in storage from November - April, drove it time to time, however the battery was dead in April. Took it to advance auto parts and they tested it and said it was fine (after i recharged it for a couple of days). Battery is only 2-3 years old.

Ignition switch is new, as the repair was done last summer.

Codes:
p1035 h c
p1041 c
p0155 h c
p0161 c
p1571 h c
p1689 h c

tcs no comm

b0432 h c
b2573 h

sdm u1040 h c

ipc no codes
radio no codes
99 hac no communications

b2208 h
b2282 h
b2284 h
b2262 h
b2264 h
u1064 h

b2283 h
b2285 h
b2265 h
u1064 h

scm no codes
bo-rfa no codes
no more codes

What do you fine gents think?

My HVAC went dead a few years ago too, had to have that repaired. When the batteries go dead, car throws codes too. If you recharged the battery and the car runs fine, clear the codes and see if any come back after driving it. Report back here with more codes if they pop up.

Thank you, will clear the codes when I get a chance tonight.

I recall getting oxygen sensor codes about four summers ago with a check engine light, I cleared the codes and the check engine light went away. Should I have repaired the oxygen sensors back then?

Car only has 45,000 miles on it currently.

Probably not a bad idea to change those. I changed mine too a few years ago

I cleared the codes, went for a drive, the check engine light went away almost immediately.

The traction control and abs logos stayed on, HVAC wouldnt turn on at all.
After 10 mins or so of driving, the ABS logo went off and HVAC turned on.

Should mechanic look at the o2 sensors? I am not handy at all to check and diagnose them.

no communications means your car lost the ability to communicate with one of the modules and since that code was an h code that probably means it regained that ability. So possibly a ground issue? See the sticky posts.

HVAC screen dim is usually cold solder joints on some resistors and easily fixed (I think ABSFixer will repair them if you don't want to do it yourself) using the information in the sticky posts.

HVAC dead is a different issue with many potential causes.

Oxygen sensors are easy enough to change if you have the tools and can get to them. If you can't get under your car then you probably can't change them yourself.
