So i have a 07 scion tc and my HVAC lights stop working on me a few weeks after i got my alarm installed in cali(i live in AZ). I had my LED done by jeremy from garage1217 and he did a very good job on my HVAC led's so i know its not the led's that are the problems. jeremy had a problem like this with my HVAC but luckly he had a extra one and replaced it with that one and it work just fine.

Then months later after getting my alarm installed it just stop working a few weeks later. Some of my HVAC lights work until i turn on my headlights then they just turn off on me. i just want to see if anyone knows how to fixs this problem or maybe i can go to the dealership and maybe get it replaced but i dont know it they will honer my warranty on my HVAC because of my aftermarket LED's

it sucks driving at night and you cant even see the time.

are 2 threads necessary? DOUBLE POST!!!!

 

^^ sorry for the double post.. but sometimes a man needs to go the distance to get his tc HVAC fixed. LOL even if it means double post.

 

Hey man, looks like it is suffering from the 07 hvac issue like your original 07 hvac did. They go out with led swaps performed and without them performed. I do not have another 07 laying around, but the best bet for this to not happen again would be to use an 08 HVAC unit. Will pm you with more details.

 

I'm sure you are working something out...but i was going to suggest pulling a switcher-ooski before you take it back to the dealer if that is what you choose to do. Jeremy should be able to take care of you.

Oh, and Jeremy, PM me your address(I lost it) and I'll have my gauges to you ASAP.
