I followed the link but was unable to find any data that would help. At
this link there is an ad to sell trouble shooting manual but after
paying the $18.99 was unable to download the manual and the contact us
link where I sent two questions was also ignored, I cancelled my order
because I need my car and can't wait around while the internet gods work
to complete transactions.

Still driving around with no fan ..................................
overheat?
