*FIXED* Broken Heater/HVAC... Replaced blower motor, resistor & relay. STILL NO AIR!
So this is getting really annoying...
One morning I started my car and my heater wouldn't turn on--no air, nothing. I left the console controls ON at setting 4 even though it wasn't working. After driving for several minutes it *magically* turned ON and I was greeted with a nice blast of hot air.
I assumed a finicky Mazda electrical system was being affected by the cold weather.
For several days this happened. I would start the car, drive until the cabin was somewhat warmer and then *BOOM* the heater would "fix" itself and turn on.
Sometimes I fiddled with the control console dials when it wasn't working. Leaving it at 0, then twisting it to 1-2-3-4 and back, or switching to defrost/main-vents/feet etc. trying to see if I could get it to activate. Several times it would turn on during my *fiddling* or if I hit a sharp pot-hole in the road.
Then one day it never came on. It has been broken completely for over a month now.
I replaced the Blower Relay first. Nothing. I then replaced the Blower Motor--hoping to go for the jugular. Nothing. Finally I replaced the Resistor--even though I was certain this was not the problem. Nothing.
Ugh. Replace the console controls next?
Any advice?
