Cassi Creek: Pathfinder follow-up –The only way to repair the climate control system is to remove the AC/GPS/Radio , send it in to Nissan, and hope that they can replace the five little buttons that control the AC/heater. This will leave a hole the size of a 12 volt battery in the dashboard for however long it takes to rebuild and return the unit.
There is also the matter of a catalytic converter that is no longer functioning correctly.
These two repairs will cost about 1/4th of the current purchase price of the 12 year old vehicle. However, the Pathfinder has been well maintained and has slightly less than 98,000 miles on the odometer. I’ll make a few phone calls next week to see about prices for repairs.
