Hi all. I have replaced a few 30A fuse for the a/c(#21) til I ran out of spares

The fuse was alright when when ignition off, whe I turn on the ignition, the fuse just pop, at the same time the interior fan was blowing on high speed just before the fuse pop, then it stop. The a/c light was not on.

I've read the FAQ reagarding the a/c repair. It sound complicated just to remove the centre console, as I think I am not very confident in removing the centre console. I bought more fuses and planning to give it another go tonight. I like to believe the car pug is sometime temperamental.

What lead to this? Recently I have a few issue with starting up the car, due to the new replacement battery is slight lower height than previous battery, the positve connection on the battery sometimes does not contact properly. In most case, ignition was ok, fuel pump running, and it just click when I try to start the engine.

I just move the positive cable on the battery and it start. Same thing happen yesterday, I notice the car start up, but the a/c and blower is not working...

Just wonder if anyone have similar issue? There's a short somewhere, fuse blown everytime on ignition grrr...

That will more than likely be the diode, i'm afraid your gonna have to remove the panel to fix it. If you print out the FAQ so you've got it in front of you and take your time it's not a hard job, and if you get stuck or not sure on something i'm sure we can help.

LOL good luck getting the zener diode from pug, the parts guy will look at you as if your speaking Martian or something then try and charge you a fortune for a new a/c control circuit. I've come across the diode on line before but haven't found anybody who sold it. The circuit will work fine with out it but it's not protected from the voltage spikes etc in the supply so it's life may be shortened.

If anyone can supply me the diode code or number or any form of idendification for the diode, I can get them from my boss

Got a quote for the SLD24-018 diode... 14.75 USD each (minimum 5) plus 35 USD for shipping to aus from uk. Good? Bad? Any comment?

I'm going ahead with it

Alright. I've place an order for minimum 5 diodes. But if you are in UK, why not try to get it from Apex Eletronics, they are the only one in the world who still have 5 in stock. I bought the other 5. It's very overpriced, 100USD for 5 diodes.

http://www.apexelectronics.co.uk/ speak to Russell Taylor. More contact info can be found on the website.

so are these the correct diodes? and do you just have remove the old one and solder in the new one?

I found out the diode from the marking it was previously made by STMicroelectronics (http://www.st.com/stonline/index.htm), those made by Littelfuse has different marking on it. All the physical dimensions are correct

Not too sure if the the right one, or if they change the spec. Atleast from the board it shows it is a bidirectional diode... there still a chance it is not the right one.

Well, I got an e-mail, mine was shipped on Tuesday, grrr... still pricey, well, just be glad it still cheaper than a new control panel and your panel got 4 more lives. Will let you know when I get it here. Hopefully today or tomorrow, I paid 35bux for the shipping!!!
