1989 XJ6 - Heater fan working sporadically

Hello:

My name is Chris, and I just picked up a 1989 XJ6 base model. So far, I have cleaned it up, mounted and balanced new tires, installed new front pads and rotors, and chased down a PS leak. I also will have to sort the horrible electronic dash in the future.

But now the heater fan only works when it wants to! I can hear a click when I turn the main fan control knob, but no fan. Yet sometimes it will kick on.

Any ideas?

Thanks so much.

Hi Chris!

Welcome to the Jaguar Forums, and congratulations on acquiring your Jaguar!

At the link below, there is a wealth of information on diagnosing issues with the blower fans (there are two of them) and many other systems:

Jag-Lovers XJ40 Ebook

Here are a few other documents to help with your renovation and maintenance:

Haynes Jaguar XJ40 Repair Manual (missing chapters 7 and 8)

Jaguar XJ40 Electrical Guide 3.6L 1988-1989

Jaguar XJ40 Power Hydraulic System Manual

Cheers,

Don
