Hi,

This all started when I disconnected the battery to check my floppy headlight issue. Prior to negative battery disconnect, the ZR was running great. No warnings. After I reconnected the battery I had a INFL REST light on with, I presume, a code set. I disconnected the battery again to see if the light reset. It did. This AM I turned on the Climate Control A/C and there was no A/C. The comp. clutch would not engage. There was a flashing indicator lamp flashing indication a fault code in the system. Ran the diag routine and got 00, no faults. Searched the site and found one reference to disconnecting the battery and rebooting the A/c controller. Did that and the A/C works great. Should be done but now I have a service ride control indicator and I still have the Infl rest light on but the A/C works great.

Something is happening when I reconnect ground at the battery because as I connect the ground the floppy headlight clicks and stutters very bad and I wonder if that is somehow not establishing a quick clean ground. It is difficult to establish ground quickly with the goofy side terminals. Perhaps I should temporarily disconnect the headlight motor until ground established.

Any thoughts on all this is appreciated.

Thanks

Don
