I dont know what the problem is but I can not increase the heat as soon as i get in the car. I have to drive the car for a good few hours before I am able to freely adjust the heat.

The crazy thing is that I am able to decrease the temperature at any time. The passenger cooling/heating button works fine.

Secondly, the top row buttons (Auto, A\C, fan increase, etc.) only work when I drive for hours. I cant turn the heat off or decrease the overall heat in the car because I wont be able to cut it back on immediately.

Any suggestions?

 

I've never seen that before... It seems like a faulty unit. It should never take a few hours to do anything. If there is no fix or any other suggestions I'd say buy a used one on ebay and it should be plug and play.

 

Does anybody nearby you have a Maxima that you could swap the heater controls to see if the controls are the problem?

 

Ok, thanks

 

Not that I know of, but I guess I'll just have to replace it. Thanks

 

Post up your location, there has to be somebody relatively close to you. It's only a few minutes to swap over the HVAC controls to see if that's the problem.

 

who here lives close to unlocated ?

anyone ?

 

Had to replace my alternator master fuse and Nissan said jumping the batt fried my radio? At night all the lights come on on the radio but it won't turn on? Also the display unit above it won't come on only ac display. Does anyone have an idea if so please send me a pm

 

I've got an 07 Bose headunit if you're interested. I removed it at 24K miles...worked perfectly when I took it out...I replaced the entire audio system.

 

Heat and electronics don't mix too well. You might have a short. Check ebay or your local junk yards for a replacement. If a replacement doesn't fix it, you might have a problem with the BCM. That is not a cheap repair. don't dump alot into a replacement switch, just look around and see if you can get it cheap or borrow from someone else to see if that is even the problem.
