A Couple Of Oddities...
 

So having driven the H2 for a few weeks now I have noticed a couple of oddities I thought I would ask about here.

First is the indicator light on the 4 wheel drive selection panel. 99% of the time the yellow light next to 4H is on, however every once in a while the red light next to neutral comes on and stays on for a while. There is no difference in how it drives, the light is just different.

The second thing I have noticed is that once in a while when I get back in and take off, the recirc on the A/C has turned off. In other words when I shut the vehicle off, the recirc was on, then when I restart and leave, it has turned off.

Anyone else see either of these minor issues?

My 4 hi light is always on....never switches as described above.

Which button is the air recirc?

Re: A Couple Of Oddities...
 

next to the off button I believe. I know mine usually never defaults to recirc so I always have to turn it on. Also it will only go into recirc if you are using the top vents or top vents/foot vents.

The red neutral light is a common problem and is related to the buttons getting old. Come to a stop and select 4H and the light will go out - at least that's what the dealer told me to do. Then at a stop cycle through the 4X4 buttons. This is a problem that for many people just seems to go away after time. I had this when my H2 was new and they replaced all the 4X4 buttons under warranty and it was fine for 4 years and started doing it again for a few months and then it stopped on its own and I haven't seen the red neutral light in over a year now. I also got a service 4 wheel drive light once on the message panel with the red light on and the dealer told me to come to a stop, select 4H and the message went out and never came on again. My recirc does the same thing as yours does on a random basis.

My recirc button does something like that too but figured out that I when I put AC on to wait 2 secs before hitting that recirc button. If u do this it comes on every time and stays on.

My AC recirculation button does the same thing. I have no problem with the lights for 4x4 though. Common problem though.

Re: A Couple Of Oddities...
 

Has anyone thought that the AC recirc is switching off because he might have programmed it that way when setting his seats and such?

I know on my Vette if you program driver 1, the seats, mirrors, radio and a/c all adjust to the programmed driver 1 setting.

I think the H2 does the same thing

Re: A Couple Of Oddities...
 

It isn't off all the time when I start it up, just every now and then.

Re: A Couple Of Oddities...
 

sounds like a programming glitch or possibly a short

given, do you remember if you turned the recirc off prior to shutting it down the last time, could be using the memory last function

Re: A Couple Of Oddities...
 

I think the A/C Rec button has to do with the air temp setting on the A/C panel
and the fan speed , plus the outside temp around the truck at the time you use the A/C

I always leave it on because it blows harder with it on. I think it has more to do with other settings as mentioned above, and not an electrical issue.

With the 4X4 lights, I'm leaning towards either a switch with a intermitant short, or loose wire. Earlier today while sitting in a drive-thru when I had the stereo turned up, the beat of the music was making the neutral light flash. I pressed the 4HI and the light started blinking, then I got the service 4X4 notice on the dash. Shut off and restarted and it went back to normal.
