FUELER Posted March 11, 2009 Share Posted March 11, 2009 auto climate control is out of its mind (fan speed is flashing like a techno party) and if i press off it just turns right back on climate control going crazy and it kills the battery any advice???

edicer2 Posted March 11, 2009 Share Posted March 11, 2009 well i would unplug it for now and see if someone has a spare for cheap my guess is that the controler is broke. I have mines older but thats what i would do Link to comment Share on other sites More sharing options...
Kingman Posted March 11, 2009 Share Posted March 11, 2009 unplug it! Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted March 11, 2009 Share Posted March 11, 2009 I had no idea climate control units housed techno parties... ...But yeah, just unplug the b*tch, Fueler. Link to comment Share on other sites More sharing options...
morpheus Posted March 11, 2009 Share Posted March 11, 2009 Most likely it's the fan amplifier (similar to fan resistor on manual air). Pretty common. Link to comment Share on other sites More sharing options...
BowTied Posted March 11, 2009 Share Posted March 11, 2009 Most likely it's the fan amplifier (similar to fan resistor on manual air). Pretty common. I just replaced mine. In my research, the common failure mode was fan stuck on high (regardless of button presing, not even off). But it would stop when the engine was turned off and did not affect the battery. You could try and swap that, but (at least for my '02) it is at least a $100 part on ebay, closer to $200 at the dealer (non-returnable). Morpheus knows better than I do, just saying don't rule out the head unit. Link to comment Share on other sites More sharing options...
FUELER Posted March 11, 2009 Author Share Posted March 11, 2009 i unplugged all components of the blower completely and the main control kept going crazy now i have removed the control (Nissan call it "AC auto amp") and i will go drive in a bit to see if the battery keeps dieing luckily the digital climate control is only $30 off ebay, the pathfinder one should work, right? (the G20 one also looks identical) Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted March 11, 2009 Share Posted March 11, 2009 All universal parts between the the QX4 and the R50 as long as the year corresponds. I'm trying to find all the hardware to get that digital system in my R50; the dials are so archaic. Link to comment Share on other sites More sharing options...
FUELER Posted March 12, 2009 Author Share Posted March 12, 2009 my advice is to keep the dials! Less electronics to go haywire. (are the dials electronic or mechanical?) I'd switch to dials if it was an easy swap. Link to comment Share on other sites More sharing options...
FUELER Posted March 12, 2009 Author Share Posted March 12, 2009 since removing the AC auto amp, my car has been starting first try (but weaker than normal) how long do i need to drive around for, until the alternator fully charges the battery?

Kingman Posted March 12, 2009 Share Posted March 12, 2009 I've seen too many electronic units like that go bonkerz to even want anything to do with one. Ever. Give me some good ol' reliable mechanical dials and levers and I'm set. The less electronics to mess up, the better. And it's easier on your wallet.

Hour on the highway should be good if everything is working right. How old is the battery? Link to comment Share on other sites More sharing options...

I'd prefer that.... but I wanted leather seats more (family rig... for now). Can't get an LE without the auto A/C that I know of. Link to comment Share on other sites More sharing options...
FUELER Posted March 12, 2009 Author Share Posted March 12, 2009 Hour on the highway should be good if everything is working right. How old is the battery? the battery is around 2 years old. Its a generic Interstate. ive done two drives so far 15 mins each. so not enough yet. but i am happy that at least its starting first try. Yesterday, it was taking me 5 or 6 tries before it would turn over strong enough to start. Link to comment Share on other sites More sharing options...
FUELER Posted March 15, 2009 Author Share Posted March 15, 2009 well the 2 year old interstate battery was bad.... would not hold a charge. Alternator is in great condition 14.4v at all rpms. got a new wal-mart battery. now, to plug the climate control back in and see if it behaves ....

FUELER Posted March 18, 2009 Author Share Posted March 18, 2009 can you believe the A/C gingcrazy was due to a bad battery? the battery wouldnt hold a charge for 2 mins but the alternator is in great condition, im wondering why the AC went crazy even with the car getting 14.4V? either way, problem solved with new battery Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted March 18, 2009 Share Posted March 18, 2009 Good stuff. At least the battery's an easy replacement... Link to comment Share on other sites More sharing options...
colinnwn Posted March 25, 2009 Share Posted March 25, 2009 (edited) can you believe the A/C gingcrazy was due to a bad battery?im wondering why the AC went crazy even with the car getting 14.4V? Wouldn't have been my first guess, but not surprising at all. Your battery had a short, and was probably dragging the system voltage down to 12v or below even with the engine running. The battery may have also been throwing off electrical noise. Apparently the AC controller is very sensitive to low voltage/bad juice.
