Red Mosquito

The HVAC blower stopped working so I was checking the interior fuses and I pulled the wrong one and dropped it beneath the fuse block. I can't get down in there. Out of frustration I just started the car and the AC was NOW WORKING but the windshield wipers WEREN'T!?! It turns out the missing "fuse" I dropped was the "accessory diode". What does this do? Does it have to be in there? Why would this have happened?! PLEASE HELP cause google doesn't have any answers.

You drive a rendezvous? Yuck.

bought it cheap from mom.. it's OK don't be a snob.. we also have a 2006 pontiac G6

I thought you were doing well financialy.

a little better than paycheck to paycheck... not great

I see.

Is this what you need?

I can't tell.. probably.. can I just walk into a local auto parts store and say I need a tiny diode? My main question is do I even really need an "accessory diode"? Why would removing it fix the HVAC blower but kill the windshield wipers? Maybe it was just removing and plugging back in the fuse that fixed the blower? Why would the wipers die?!

I fucking hate this shit. Why do cars have to be so complicated?

Those are all very good questions, but I can't answer any of them.

I think the best course of action is going to be replacing the diode and blaming the whole incident on shoddy GM engineering.

yeah that's what i figured.. it just doesn't make any sense

The accessory diode probably acts as a relay. If that's true, it'll power up other things when you turn the key to acc and on. Get another one, pop it in, and hope. Debugging electrical issues in cars can suck.

A diode simply controls which way current flows to your flux capacitor. Removing it has probably created a matrix issue. Best to pour some nether fluid over the block to cleanse it of particle waves.

turns out I have to pay 300 to have the blower and resistor replaced

that sucked.. fucking hate the burden of vehicles
