2003 Accessory Delay Relay Power Drain

[tomlogan]

I have a 2003 Explorer XLT v6 2wd. I'm setting it up for a trip out west - camping in the car some. I want to be able to lower the electric windows without turning the ignition key. From reading here - I concluded that the accessory delay relay drops power to the windows and the radio. I therefore installed a switch across the contacts on the delay relay - problem solved I thought. As it turns out - when this switch is on (bypass relay) the car battery dies - with the radio off and the windows left untouched. I measured the current from the battery and discovered that the drain on the battery is 1.0 amp when this relay is bypassed - radio off. So it's obvious there is one or more other things getting power from this relay. Any ideas as to what else is on this circuit?
Thanks
Tom

Do you have a factory subwoofer? I believe the accessory relay turns the power on for the amp...

There is no subwoofer I know of. It has the basic radio/cd/cassette unit. It's the factory original - single cd unit

I tried a little test tonight. While I had the relay bypassed (such that I had the 1 amp draw), I flipped the air conditioner knob to different choices. I could hear what I assume were the dampers switching positions. I'm now thinking the drain has something to do with the air/heat system

Nope, they're moved by vacuum not electricity and the blower is on the ignition relay not the accessory relay.

Ah. That makes sense then. Thanks for that info
