Rep Power: 0 blower problem
OK, the a/c on my daughter's 2003 Civic stopped working the other day. Hot day, a/c on and working fine, and then suddenly it's off. No blower. Looking carefully, neither blower or compressor are active. No heat, no a/c no nothing. Have had no troubles with this system before.
I'm reluctant to believe it is the blower switch, because the failure didn't happen when the switch was being turned.
I removed the blower motor resistor/transistor, and it checks out fine. 1500 ohms between pins 3 and 4.
I've checked fuses, though it isn't entirely clear which ones are relevant.
FWIW, the indoor filters were pretty dirty, and I cleaned them out. Maybe that led to the problem?
Where do I go from here? Help appreciated.

If you think a good mechanic is expensive, try hiring a bad one
Re: blower problem
Blower MUST run or the HVAC computer will shut off the AC system.
Inspect/test the blower power transistor. If it's shot then check the cabin filters and amp draw of the blower.
