$208 from www.jaguarparts.com . (Davis Automotive Group, very reliable)

I have ordered from parts.com , but they are a clearing house from dealers all over the country and you get no customer service until the part comes. The part comes from a dealer that agrees to sell the part at the advertised price. If you have a problem with the part, you can then deal directly with the selling dealer.

My local jag dealer usually charges 1.5% more that the suggested retail price for parts!!

 

Hey, thanks for the info. I got the glove box out and installed the part this weekend. It was man vs auto and I was winning up to the end. When re-installing the glove box, I wad putting in the screws inside the box. I closed the lids and now it will not come unlatched and will not open. Does anyone have a trick to get the glove box lid open, so that I can get it adjisted correctly?

 

Thanks Brutal!

 

The lovely part about this is that when you look at the wiring diagrams in the JTIS for both 2003.5 and 2004 XJ8; the wire colors are wrong. Jag shows blue where I find black. There is a plug at the fan and one near by and both have heavy wires. The white is the POS feed. The plug away from the fan on mine goes on and off with the Climate Control switch. At the fan the NEG goes on for just a moment and then goes off. So, the fan will spin for a moment and then quit. Looks like I am in the same club.

 

Hey long time no see, nice to see you back .

 

To quickly test the blower, disconnect the blower control and connect the two black wires in the harness with a jumper good for 45A. If your blower goes on and off with the fan speed in the climate control, you can rule out a problem with the blower itself.

I made the following jumper out of 12 AWG stranded copper, two male quick connects, and some heat shrink tubing. It runs the blower and does not generate heat.

 

The test of the 2004 and up X350 XJ8's fan is easier than that. The panel above the foot area on the passenger side drops very easily. At the fan are two wires. The white one is the Pos and the other one is the switched Neg. With the climate control on jump the dark wire to ground. If the fan is good it will spin.
I'm going with Brutal on this.

 

Hi see all the post I was wondering I have a 06 jag vdp is there two blowers or one and where is it located thanks in advance

 

I have just bought my second Jaguar, 2007 XK convertible 17,000, and the dealer told me that the local Jag dealer had just had the drain tube unblocked and everything seemed to be working fine. Had the car a week with A/C working fine. Then suddenly the blower will not work. This goes on for two days, I wonder if the failed drain tube effects the blower module in some way and causes it to fail. Strangely when the temp dropped a little in the last few days the blower came back on and has not failed since. Has anyone had experience like this? Rock Auto parts has a direct replacement for the blower module for $68 with the same heat sink as the original version but Jaguar now sells a replacement with larger fins for over $200. Has anyone experience with the Rock Auto replacement part and it's longevity? I can't find a diagram or method to show how to remove the glove compartment on this vehicle, help anyone?

XK 2007
XJ6 C series 1987 (sold after 22 years)

 

The Jaguar module with bigger fins was produced because the previous modules got too hot and failed. This happened to me about 2 years ago. If you're happy to have to replace this module regularly, then go for the Rockauto part. Much depends on how long you're going to keep the car, but the Jaguar module should last longer.

 

Hi gdollar,

Welcome to the Jaguar Forums!

For the record, you've posted in the forum for the X350, the '03-'09 XJ sedans. The blower control modules for the XK and XJ are different part numbers. However, they are probably functionally identical (power transistors used as variable resistors to control the fan speed).

When the blower control module failed on our '04 XJR, I first rebuilt it with a new power transistor and thermal cutoff, but I used the original short-finned heatsink. It failed again on the next really hot day. So when I rebuilt it again, I used a salvaged heatsink purchased on eBay, which I cut down to the right size. The module has been working for almost a year now and if it makes it through August I'm going to consider the repair permanent. Here are the details:

Also, since we're a friendly group, please visit the https://www.jaguarforums.com/forum/n...-intro-must-5/ and post an introduction so we can learn something about you and your Jaguar and give you a proper welcome.

Cheers,

How would you decide whether the motor or the relay is bad?

 

See Post #28 from sleepyastronaut for an easy test of the blower fan motor. If the fan runs, the problem is almost certainly the Blower Control Module. See the link in my Post #33 for instructions for repairing the BCM.

Cheers,

Don

 

Talk about planned obsolescence! The blower control went out on my '06 yesterday. 94k miles. Already ordered parts per Don's excellent how-to post so I can repair my module.

 

I recall that when I replaced this module in my wife's XJ8, the part was found to be interchangeable with the improved version found in the XK8 (larger fins). That was 2 years ago, no problems since.

 

Hi SaturnV,

I've heard the same from at least one other member, but I haven't been able to confirm it based on the Part numbers.

According to jaguarmerriamparts.com, the latest part number for an '04 X350 XJ is C2C39577, and for an '08 X350 XJ it is C2C12905.

The latest part for an '04 X100 XK is JLM11959, and for an '08 X150 it is C2Z6538.

Would you happen to have a record of the part number of the BCM that was installed in your wife's XJ8?

Thanks!

Don

 

So if I just connect those wires together and throw the blower control away, I'll be able to control my fan speed instead of having that crappy automatic climate control?

Do you know a way to disable the temperature controls as well, and change it to just "hot" and "cold"? I hate the climate control. It alternates blowing hot air and cold air on me in the winter. I hate trying to guess what the temperature is inside the car in order to get hot air instead of cold.

 

Hi Xeno,

Unfortunately, if you simply jump that connector you would not be able to control the fan speed. You would just have full fan speed all the time. You could substitute some sort of manual control circuit for the BCM, perhaps a rheostat with a suitable resistance range and power rating....

On our '04 XJR the automatic climate control works quite well. I wonder if one of the sensors in your system is malfunctioning? Have you ever had the system scanned for fault codes? I think they would probably be B (Body) or U (Network) codes, so you'd have to scan with a system capable of reading the proprietary Jaguar codes.

Cheers,

Don
