The parasitic load on this vehicle will discharge a FULLY

CHARGED battery in 21 days. What is the condition of your battery

and the climate to which it is exposed? You can check to see if the

load on this vehicle is excessive. Parasitic (Sp.?) should be 0.07

amps. If over this check as suggested by next answer. Something is

drawing power. Possibilities are a under-hood light, courtesy

light, glove box light, etc. Another possibility is that the

battery needs replacing. vehicle is 2005, is battery the original?

sounds like the battery needs replacing a battery that sits idle

does not have much of a life span
