The Nissan Path

Hello all

I do have 2015 nissan pathfinder, my problem is that there is no heat, the flow is normal, the engine heat is normal, I can barely feel warm when it's at 32 Celsius!

The coolant is on the maximum, and I tried to burb it, but nothing worked.

I took it to the dealer, they couldn't find anything!

I believe there is a blockage in the heater core, and I think it needs Flushing of the heater core..

Any ideas?

Thank you

What did the dealer suggest?

They changed the cabin filter and added coolant.

Then asked me to come back later!
