|ZeRoSL||Drilled holes, no water came out, so i guess my blower motor probably fried and there's a short somewhere. I may need to get creative|

|ZeRoSL||thanks, I'll drill the holes and report back|

|ZeRoSL||Sorry to clarify I replaced the fuse once, then turned on the car, then went to turn the air knob and it popped again|

|ZeRoSL||All fan settings do nothing|

|ZeRoSL||Ok, after testing continuity all the fuses tested good, but then i tried to turn the knob to 3 and it popped again. What does that mean? I know that means too much current, but not sure what too much current actually means.|

|ZeRoSL||OK will report back after testing|

|ZeRoSL||I imagine, if i replace the fuse, and i turn on the fan again and it blows right away, what would be the next step to check? Does that mean the resistor pack needs replacement? Is there any way to test the motor itself?|

|ZeRoSL||Thanks I'll grab a voltmeter and go through the fuses again and check C1 tonight. Thanks CYOW5|

The only way I check a fuse is by removing it and measuring the resistance across the terminals. Sometimes it is not visually obvious that it is blown, so this is the only surefire check.
The flash you saw was probably fuse C1 for the blower

Troubleshooting steps for HVAC issues
Hi all, I was hoping to get some help troubleshooting and testing steps in this thread to get the easy stuff out of the way before coming up with a game plan for fixing my HVAC.
It seemed like all of the steps to troubleshoot were scattered about all over and I thought it would be helpful to have it all in one spot to help myself and others in the future.
It seems like the steps to check in order of difficulty is
2) HVAC Controls
3) Switch Pack
4) Blower Hot/Cold Flap and Flap Actuator
5) Resistor Pack
6) Blower Motor
Now, which fuses should be checked and what are the locations of them all? How do I check the HVAC Controls?
Anyways, for my specific situation, I would appreciate any help as well.
What is not working: all 3 fan settings see no life. Recirc button never worked/lit up. Hot/Cold actuator flap does not move.
What I did check: heater core flap is not stuck, I can move it with my hand. I believe I checked the fuses, but am not 100% sure if I am checking them properly or if I am checking the right ones.
What I want to check, but am not sure how: Check all proper fuses and locations, check controls in cabin.
I bought the car and recirc light never worked, but i didn't bother with it as everything else worked.
Then one day the flap stopped working, but I just manually moved it a few times a year.
Then after a heavy rainstorm, I went to drive it and as soon as i turned on the fans, i heard a POP, saw a flash under the dash above my feet and the blower stopped working after that.
I appreciate any time/help/pictures/links to instructions and such.
