issue with malibu horn system and coolent

ok im new to this form and not sure if this has been posted in the past or if anyone has or has had a simmler issue.... (well this is part 1 of 2) when im driveing around town or just for a while doing a paper route ect my car will for no reason known to me just honk not long just *beep* dunno if shes just hittin on other cars or what. and its just random could it be a fuse or wireing any advise other then take it to the shop would be helpful.

the next issue is my coolent systemand why i hate shops....
when the weather gets cold my coolent reader stops working and my light turns on i mind you only when its cold out like late fall to early spring car runs fine no problems. the shops i took it to gave me different reasons one said its the thremastat another said that it was just the internal radeator seal another said it was the lower intake manafold another said it was the water pump. and the list goes on and no shop said the same problem and the others. any help with this issue. well its not as bad as my old vw jetta thats for sure thats another post:runaround: :screwy:

did you look in your rateator a see if it was cirulating? then there a coolant sensor that go's in the side of the raitador and for the intake try to do a compresion test but not sure your sensor in the side of radiator but most are in the side of radiator on coolant sensor.
