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).
The previous two examples have suggested how we should define the measure formally. In short, the coefficient of determination or r-squared value, denoted r 2, is the regression sum of squares divided by the total sum of squares. Alternatively, as demonstrated in this, since SSTO = SSR + SSE, the quantity r 2 also equals one minus the ratio of the error sum of squares to the total sum of squares:
