hi, james here looking for any help i can get here before i go and buy "the big camry book for dummies"!
symptoms:
1. turn the ignition off, dash lights "fade"
2. electric radiator fan doesnt shut off, have to unplug
3. battery dies
any thoughts?

 

I'd get the battery checked. Not sure the fan run after key off is not normal. Does the fan never shut off? Where does the heat gauge sit after fully warmed up and when driving?
