Climate Control Flashing Questions - ZR-1 Net Registry Forums

I took the car to Phoenix for a day and the car did great on the trip....it was a lot of fun on the 2 laners coming back through the hills.

About 75 miles into the drive home, I stopped for a bathroom break and when I started the car, the climate control button light flashed, whichever button was selected. It flashed for a minute or two and stopped. Everything seemed to work ok after that, although I have no idea if the AC was actually working since it was very cool out, but the vents/defrost all responded correctly.

I've seen it flash once or twice before....usually for less than 10 seconds before acting normal again.

I know the climate control will flash when it has a trouble code and I have the listing of the codes in the FSM.

Since it stopped flashing, I didn't have a chance to pull the code off of it. Will it store the code after it stops flashing or do you have to catch it while it's flashing?

I ended up having to disconnect the battery last night. My LT4's lights started to dim a little here and there and when I got home from work, the negative cable was loose. I tried to tighten it but it just turned...the bolt was stripped. Because it was Thanksgiving and all the shops were closed, I had to rob the bolt from the neg cable on the Z to get my daily driver back in action. I'll get a new battery bolt on my way home from work tonight.

Obviously, I know it won't store the code after the battery's been disconnected, but I'm wondering if I see it flash again, will it store the code.

It is entirely possible that the head unit just needs to be pulled, cleaned and make sure the connections are good. Every once in a while....as in once or twice since I've owned the car about a month and a half ago, the unit will put itself into auto (then turn off fine when I hit the off button) and the raise temp button will not respond for a few pushes.
