I will take a stab at the answer....... Do you live in a hot climate? If so, when the engine is hot and possibly a new exhaust was installed, the clicking would be the exhaust cooling off. Sound good ?
The clicking sound from the air vents when the heat is turned on could be caused by a problem with the blend door actuator or a buildup of debris in the vents.
The clicking may be the belt tensioner clicking. I know that mine is causeing a clicking noise. If you get a friend to help you, you will be able to see it happen if that is the case.
Could be a faulty relay!
A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.
It depends. If it is a loud clicking sound you will want to take it to a professional Immediatly! Without Delay!
The clicking could be either of these. The starting after ten minutes sounds more like brakes. As brakes heat the problem could start. It could be an axle bearing as well. The only way to know for sure is to start checking the components.
It is not recommended to eat jalapenos that have turned black as they may be spoiled and could cause food poisoning.
Your flasher relay box may need to be replaced, but could also be an electrical short.
Could be bad ball joints.
Probably a damaged gear or bearing.
if it has an electric antena and a broken cord so it wont pull down it could click
Could have a bad motor mount
