Nissan Terrano 2.5

Hello Friends of the Forum please I need help with this truck. The problems is that in third and fourth he sucks he is left without power, instead in 1 2 and 5 he does not know what can be if someone has happened to the same please help me thank you very much

Hello, is it a TD or TDI? If it is a TDI you may fail the P/N sensor (change lever position sensor)
is very similar to the back switch and they are close to each other, to know which is best to put the march behind with the ignition on, disconnect one and check if the lights stop working. When you know what it is, you disconnect and test the car, you may pull you but the car would have to work in the same way with all the speeds. Greetings and luck

Thank you very much I will try and tell you, thanks for your time.
