Can anyone help with the below questions. Searched but cant find the answers :-(

1 - How do i remove the ciggy lighter to replace the bulb. Cant get the thing out. Ashtray comes out but cant get rest out.

2 - My car comes with no mirror in the drivers side. Can i swap out the visor for one with the mirror as cant see the power connectors in my car. Presume they are hidden in the roof liner ?

3 - Where is the coolant temprature sensor in the engine. My temp never seems to move. Only now and then it lifts over the first mark so was thinking i need to replace to sensor.

Cars a 55 plate cdti 150.

Cheers
