No heat or ac and airbag light on
 
So lastnight I did the led heat control and evic overhaul...now my heater/ac doesnt work.everyhting lights up but no fan...also Ive noticed that my airbag light chimes and stays on in the speedo bezel and the passanger air bag light in the evic doesnt light up...im thinking i blew a fuse/relay somehow...does anyone know where the fuses to these components are? Any help would be greatly appreciated.

Anyone have any insight as to where to begin with fuses...So far Ive checked all but under dash...there all good...maybe a bad relay? Keep in mond this happened after I unhooked all the hvas evic pllugs and plugged them back in...and I have double checked all connections.....anyone?

haha, on WKjeeps, it says fuse 10 interior is for ac/heater/HVAC, but for 2007-2009, u could try there though...good luck!!!

Edit: its a red 10amp fuse BTW...

Yeah, I saw that site and was hoping that will fix her, but i did notice that it says 07-09 only? what the 05 06 10 doesnt have these components lol? im gonns go through all the fuses today and see what i get...Im wondering wtf because the lights still illuminate which tells me power is getting to the unit...leaning more to the problem being something with whatever is affecting the airbag warning...Thanks for the help though, I will figure it out!

first mistake WAS TOUCHING anyting with the battery connected.

dont want to sound like an ass here but you arent working on a 62 checy. modern cars like the WK have a can bus system to handle all the communications between modules. every electrical system on your jeep runs thru these modules. These modules and the associated sensors ARE VERY costly.

I cannot say it enough.........disconnect the negative before touching anything on a modern day jeep.




......now hopefully its just a fuse and not the FCM that controls the lights.

Im sure its not the fcm...Why are you so abrasive robpp? I build elevators and am very familiar with electronics...I didnt see any need to undo the ground to unplug some plugs...thats what they make fuses for my friend. Now i just need to check them all...
