Hi Guys, Need some advice. I have a nissan patrol platinum 2015 model. When starting for the 1st time in morning everything is fine. After that when I start after a couple of hours, there is no problem with the ignition . Its all smooth starting but after that it gives out this sound which sounds like tak, tak tak... couple of times and them stops, which seems to come from the lower part of dashboard an. This varies from time to time . I feel it happens after i switch on the AC but not very sure as sometimes the sound comes in spite of not switching the AC. There is no other problem. The vehicle runs perfectly. Suggestions welcome
