Well, last night I installed an Itr climate control that was shipped from austria. I removed my climate control but didn't install the itr one yet because I had to go out and do something. So I was driving around with the climate control disconnected. When I got back home, I installed the itr climate control. I turned on my motor, checked all of the lights to see if they work. Everything worked fine but when I pressed on the rear defrost button the light didn't come on. I turn on the a/c, nothing happens. Turn off the car, turn it back on and the abs light is on. It was late so I waited till this morning to check it out again. I checked all of the fuses and everything seems to be good. Doesn't seem like there were any blown fuses. Swap back my stock climate control and i still get the same problem. I even tried checking the abs code but no codes came up. The abs light just stays on. can someone help me please.
