Glad that I've purchased the extended warranty. I've brought in my xc90 for a basic oil-change and alignment, hoping that will fix my loud road noise. The dealer told me that I had a defective bearing and a climate control module. The cost to repair was around $1500 and since I have an extended warranty, I would only pay the deductible ($100). <p>I don't know if this is true but, when I've asked what is the climate control module, he mention that if this is not repaired, this may cause the car not to start. Is this true, has anyone have this replaced?
