2014 Maxima SV, all stock, no mods. Last week, the dashboard outside temp display went to all dashed lines ---- and the blower motor would not blow any air, either hot or cold. I replaced the ambient temperature sensor and there was no change. I took it to the shop and their tech ran a diag on it and said the AC control panel was not putting power out although there was power to the unit. It's a Nissan part which costs more than $1,600! The control panel includes the radio which is working fine. I trust the shop, but do y'all have any other ideas on what the problem could be or do you know a place where I could find this part, ie. online salvage yard, etc. TIA
