It sounds as though you may have a fault with the ignition switch or circuitry heading from the ignition switch to the starter assembly. <p>Typical failure of the starter is characterized by some noise, whether it is a grinding bendix gear against the pressure plate (flywheel) or a click from the failed solenoid. The only other thing I can think of is maybe you have just enough amperage on a low battery to make your electrical instruments and accessories appear normal, but not enough to kick the starter. <p>Being that we are in the heat of summer right now, I would be willing to guess that you've used your A/C a fair amount this summer, and the "afterblow" feature of your HVAC system (designed to dry out the airbox to prevent mold) coupled with your engine cooling fan have drawn your battery down and it could just be in need of a good recharge. That very thing happened on my 02 XC with the OE battery this spring. I've only recharged it and it has not even delivered a sluggish start since. <p>You have a 2003, it could be the 6 model-year-old battery if it is still original. You should have a 600 amp battery, if you go to the dealer for a new battery, go spend the extra $20~ on the 800 amp battery. And I would highly recommend a factory battery. Good Luck! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> </TD></TR></TABLE><p>I certainly agree with the fact that most non-essential electrical consumers are shut down during cranking, I have a hard time with the fans being the culprit.<p>After blow runs the HVAC fan for 5 to 7 minutes, 50 minutes after shutdown. Fan is on high, drawing about 5 Amps, for a run duration of 6 minutes or 1/10 of an hour. That could accout for 0.5 Ah capacity taken from a 60 Ah battery. Not significant in my mind. <p>I have only heard the engine fan run, after shut down, for a matter of seconds, but if we gave it 1 minute, that is 1/60 of an hour, and lets give it a 10 Amp draw. That is less than 0.2 Ah on our 60 Ah battery. <p>Add to the above the fact that Volvo battery management, on the newer cars, eliminates such things as afterblow if it detects low battery voltage. I agree that Volvo software is not the most reliable, but I have actually seen this work on my 2005 V70R.<p>If there is nothing that takes place when turning the key to "start" I would expect the antenna ring, around the key, a part of the immobilizer.
