A/C and Heater Don't work after running through puddle - LotusTalk

MidasHands · 09-30-2008, 05:50 PM

Another Lotus owner on this board ran through a large puddle of water over the weekend and his a/c and heater stopped working. The blue light for the a/c does not even go on.

Any ideas of what he can check? Fuses?

Okay, What you need to do is take a 20amp fuse with you as you poke your head upside down in the passenger seat and your feet hanging on top of the bow cover at the top of your car. look under the dash, you will find a triple block of 20a fuses and more than likely the center fuse is blown. simply pull it and replace with the new one and you should be fine. There are two set of those fuses under there. This is where they are located for the HVAC system. You should be fine except for the crick in your neck from standing on your head.

Thanks I'll check that!

My new Elise got wet for the first time this weekend. The A/C stopped working similar to the post above. It did come back to life an hour later.
Whats with that???

Gremlins...

It's British.

MidasHands · 09-30-2008, 07:13 PM

His has been out for a couple days so I don't think it is going to just come back on.

He is going to check it tomorrow in the day light.

...there's a service recall modification to drill drainage holes underneath the HVAC assembly, barring which it tends to short out or corrode due to standing moisture - my previous circuit died thusly...

LordZ · 10-01-2008, 06:38 AM

I would strongly suggest anyone without the holes drilled that drive in the rain or even wash their car to get it done. That circuit that gets shorted out requires a front clam removal to replace if I'm not mistaken.

Remember to take your shoes off 1st. Although, I think in my avatar my shoes are on, but you can leave scuff marks.

TheViper · 10-01-2008, 03:27 PM

It's the blower motor resistor pack corroding/ shorting out.

Hi

Yes it is (see picture).
I'm just finished with this job.

iben, is the bottom pic the actual lotus replacement part or did you build that yourself?

jwood · 10-11-2008, 06:18 AM

My 06 exige is in the shop right now getting this replaced. I tried the fuse with no luck. Apparently they are replacing the same thing iben has done. So far it has been 3 days! Now I get to drive a vw passat loaner!

I miss my car.

rob13572468 · 10-16-2008, 07:19 PM

well it turns out that the $150 dollar resistor pack replacement is actually $10 worth of resistors...

Graydon · 12-12-2008, 05:54 AM

FYI... just had this happen, the dealer said it would be a grand to replace the resistor pack. For sh*ts & giggles I checked the fuse and that's what it was. Saved a grand, and I am one very happy dude. ;-)

(yes I know I should've checked the fuse first, but it makes for a better story this way)

the1sen · 12-13-2008, 04:02 PM

anyone know if one can have this replaced before any issues happen on an 07?

or does the 07 already have the fix in place?

Scott · 12-14-2008, 04:12 PM

I think mine is shorted out. During the Summer, I was on my way home and got caught in a downpour. The AC stopped working. The fan would not go on... nothing. Well now the fan works, but I have no heat. I haven't tried the A/C because there is no need for it now. If this IS the problem can someone explain how to replace it?

TheViper · 12-14-2008, 05:08 PM

If the blower fan is working but you have no heat then it sounds like one or both of the two flap valves in the climate box are not diverting the air flow. You can see them by taking off the large flexible duct that comes out of the top, looking down while getting someone to operate the temperature control.
