gu patrol ac fan control

Don't solder the link, the solder used is a special heat sensitive solder thats designed to break to link if it gets to hot.

Instead of putting a bandaid on it and hoping everything is all right, get it checked to see why it has happened..... fan amy be on the way out and drawing excessive current.

That link is there for a reason.

Thanks olcoolone but it is a reasonably common issue and this is the standard fix for it apart from spending $95 for another board so I will still recommend that if someone doesn't want to buy the board that they can solder.

Not sure if you are aware but there are many posts on this in the Patrol forum spanning many years.

The circuit is still protected by standard blade fuses. The fuseable link is only for the first 3 speeds and has no affect on the 4th speed so it really has no use at all except being a pain in the ar$s when it goes.

Yes I have a technical background.

If it's got no use then why is it there?

What made it fail in the first place.

..... you too sounds different to my technical background where doing things right the first time is the only way.

But then again we have the customers best interests at heart.

Quote - "If it's got no use then why is it there?" - Exactly, even Nissan don't know. Maybe a recycled part from another model.

Quote - "What made it fail in the first place." - From what I have found, the material that is used to make the tracks is the problem. Porous graphite carbon compound that is susceptable to moisture. It is a poorly designed board.

Quote - "..... you too sounds different to my technical background where doing things right the first time is the only way." - you would be suprised. Just because the suggested fix is not replacing the board as stipulated in the service manual doesn't make it wrong.

Quote - "But then again we have the customers best interests at heart." - Always.

If you owned a Patrol and frequented the Patrol forum then you would see the issues and recomended fix on a regular basis. Of all the posts that I have seen where the first 3 speeds don't work but the forth does is this exact issue.

Unfortunately you throw your arms up and tell eveyone to hold their horses but you do not have an idea about this particular issue. Sure you may have some fault finding experience and your suggestion of circuit testing has merit in most situations but my recommendation was based on not only my experience but also those that have also had this fault as well.

Some decide to go and buy the board and fit it up themselves because they are not comfortable soldering the link. It still fixed their problem but did they measure the resistance of the fan circuit first to see if there was a short - no they didn't. Ring up Nissan and ask them and they will tell you it is a common fault and to come in and get the board.

Now you may reply with some quote on technical ability of fault finding procedure so I will make the suggestion not to bother as it will be a waste of your time.

Thanks for reminding my why I didn't continue my membership here. Posting here is like pulling teeth sometimes.

Thanks again,

But is the fusable link part of the resistor board next to the fan under the glove box on the flat board(fan resistor) thing held in by 2 screws?

Thanks craig v

Thanks everyone,
No need to argue whos right and whos wrong but I know if I take it in to get repaired they will say every thing needs to be replaced because its a nissan! I think it is the resistor and nothing major because it works ok on high or 4, I think Ive looked at the resistor board if its the one under the glovebox next to the fan flat plate thing held in by 2 screws?

Next thing , has anyone heard of a 3l engine lasting more then 250000km??

Good to see Robin that you want to know the cause of the problem and rectify the cause instead of engineering a solution.

Too many people forget to diagnose the root cause and act on that.
