Hey People,

So now that's it is getting cold down here is southern Cali, wife went to turn on the heat and all we get is cold air.

Any thoughts or ideas?
I read some posts about blocked heater cores.
Is this a a good start to check?
I didn't see any fuses in the manual stated the heater.
I am going to be getting under the dash Sunday just need some pointers on what to look for.

Thanks Kevin
