The same blower is used on the left and right sides. Please note the right-side blower is the more difficult of the two blowers to replace. The mounting bolts that hold each blower are hidden on the right-side blower. Each blower is supported by a bracket with 4 screws, 2 on each side of the bracket. Removing the screws releases the bracket and blower assembly and allows for installation of the new blower onto the original bracket. Please note: Does not include mounting plate and hardware, so you’ll need to re-use the OEM mounting brackets, rubber grommets and brass spacers from original kit if required. In most cases, the blower will mount to your existing bracket with little to no alterations required. This blower produces just as much air flow as the original, uses superior bearings and has a more efficient motor. If you’re installing a blower for the first time, a blower kit may be required. Replacement blowers are intended to replace worn or defective blowers and do not include the components of a full blower kit. L x W x H. 15 1/4″ x 4 1/4″ x 3 9/16. 12.0″ x 2.0″.
