This weekend I put in a Pioneer AVIC Z3 system into my 05 TL. Two issues came out of this installation and I don't know if they are related or not.

I didn't notice until now that the HVAC red and blue arrows to control the temperature isn't illuminated on the driver's side anymore. The passenger side is still lit whenever I flip the headlights on. It's only the driver's side arrows that are now completed blacked out.

The second item is the front side marker on the passenger side is no longer lit.

What can be the problem? It is probably worth mentioning that we worked on the car all day, enough to drained the battery. I had to jump start the car obviously. Could this of have cause the problem? Did I blow a fuse or something?

Please let me know your thoughts and opinions. Thanks.

 

the bulbs are blown. happens all the time when you disconnect the switch.

 

How much are these bulbs usually? Are they easy to replace? Thanks again.

 

there like 2 bucks. just need to take the switch out and a flat head and they half turn out
