Hi All,
My first post here.

I've had my X350 XJR for a couple of months now and very pleased. However, the blower has stopped working. The controls from the dash are fine, just no hot or cold air. I've checked the 40amp fuse in the boot and that's fine. Anybody any ideas what next to check please?

 

Thanks zvonas but it's the cabin blower that's not working.

 

don't suppose you have a link do you? I searched but couldn't find anything.

 

there are 2 blower motors 1 on each side and if one quits, the air from the other blows across so you get very little air if any at all from the vents, yes you must replace it. but they do not go out other so you can get a recylced 1, to determine which 1 get under the dash and feel each 1, the drivers side is a pain to do as must drop the column, pass is easier

 

Up to 2003 there were two blowers, the 04 and up have only one behind the passenger air bag. This motor is designed to be easy to remove, you can remove the passenger underscuttle, remove three boltsand jerk it out and test it or remove the connector and test it in place. There is a remote climate control module that operates it and the harness or module may be involved. My first move would be to open the instrument panel closer and wiggle the pertinent wiring first.

 

CRAP SORRY DIDNT SEE THE 04 AND UP, ITS THE BLOWER RELAY ON TOP OF THE HOUSING, DONT WORRY ABOUT ANYTHING ELSE. WE PUT THESE THINGS IN LIKE 5 A WEEK.YOU CAN ONLY ACCESS BY REMOVING THE GLOVE BOX. THE NEW UPDATED PART FROM JAG THAT HAS LARGER COOLING FINS IS #C2C39577 LIST $212

 

Checking the relay is good advice, thisshouldalways donealong withtesting the actual unit concerned. I'm pretty sure the blower relay is in the trunk power box, relay R1. I have not removed one of these blowers but I think only the wiring connector is attached to the blower. I have also heard of more than one of these blowers that has stopped working.

 

IM NOT REFFERING TO THE RELAY, IM REFFERING TO WHAT DOMESTICS CALL THE RESISTOR PACK TO ALLOW DIFFERENT FAN SPEEDS, JAGUAR CALLS IT A MODULE/RELAY DEPENDING ON WHERE OF WHAT YOURE LOOKING AT PARTS, SERVICE GUIDE OR BOOKING...FOR SOME REASON JAGUAR CANT CANT A PART THE SAME NAME IN THREE DIFFERENT REFFERANCES, DRIVES US NUTS. JUST BUY IT AND INSTALL IT AFTER REMOVING THE GLOVE BOX, THE CONNECTOR AND PART ARE IN THE TOP OF THE DUCT ABOVE THE BLOWER ASSEMBLY AND THE ALUMINUM FINS EXTEND INTO THE AIR STREAM FOR COOLING. WHEN YOU PULL THE OLD 1 AND COMPARE TO THE NEW ONE YOULL SEE THAT THEY MADE THE FINS LARGER TO IMPROVE HEAT DISSAPATION AND HOPEFULLY PROLONG LIFE....

Great information. If you are changing out that many of one item, you must be in a large dealership.

 

yep one of the nations largest in Houston, and that may be a little overestimation, but we put alot of those in. So much that this year when it started if a concern came in of blower inop we wouldnt even schedule the appoint, without that part. Thats one of those no diag needed repairs....and this was the only point I was trying to make

 

Perfect!
Thanks guys, I'll take a look this weekend

 

Go to www.parts.com and search that part number. You will see it.

 

The fault will be a failed field effect transistor and/or thermal fuse in the blower speed control module.For full details and pics see roberwil's post on Jaguar Forum.co.uk

 

There are actually three things to check when you're having a problem with your blower, First, check the fuse directly with your blower motor. second, check the connections behind the control, this includes the middle relay on fire wall under the hood, and lastly check your resistor. Your resistor is responsible in sending current to your blower motor.

 

Hey, thanks for all the great info. I talked with the Jag dealler here in VA and they want $318 for the part. Where do you suggest that I check?
