Will the engine give problems in the future as it is repaired. The truck has done 190,000km.

Are They hard to change out? How much is the cost for one?

My horn stops working one day then starts again the next and so forth. Im trying to figure out the problem. I checked the fuse and the fuse is fine. Im not sure where exactly the horn relay is located and I also believe I only have the one horn on my model(drivers side under headlight) because when I activate the locking alarm it makes the same pitch sound as my actual horn. Not high or low. Maybe the line is corroded due to rain or maybe its a bad connection or have gotten some water on the horn. Any ideas on how to fix the problem? Also I'm looking for the horn relay so I can check it. Its not in the under hood fuse box with the other fuses so maybe they put the relays somewhere else?

with a full tank what could be the problem ?please help

HVAC randomly switches to heat on drivers side when a/c is selected. Pass side functions normally. Have to play with inside/outside air selector to fix. Air doors seem to function properly, just not always as they should for the mode selected.

Is this normal for dash lights to be on when the day time running lights are on. I have a 2008 G6 dash lights are out only come on when dark. I just bought this truck so I don't know if dash lights must be on I am concerned in time if dash lights will start to burn out. Do I have a problem and if so how do I fix it please help me out if you can. I took the truck back to dealer I bought the truck from they are not a GM dealer they could not fix it I had them replace the head light switch and the senser on dash this did not work.
