The fan and motor for the blower is usually under dash on the passenger side behind the glove box. Most of the time it can be removed by removing the bolts (should be 10mm) from the bottom of the dash area. I did not get the model of your vehicle, but sometimes you will need to remove the glove box to access.
In statistics, the coefficient of determination, denoted R2 or r2 and pronounced R squared, is a number that indicates the proportion of the variance in the dependent variable that is predictable from the independent variable(s).
R-Squared Measures How Performance Matches a Benchmark. R-squared is a measure of the percentage of an asset or fund's performance as a result of a benchmark. It is reported as a number between 0 and 100. A hypothetical mutual fund with an R-squared of 0 has no correlation to its benchmark at all. A mutual fund with an R-squared of 100 matches the performance of its benchmark precisely.
