Just saw an invoice from a local dealership for replacing a cabin air filter, $69. No wonder the auto repair shops are hurting for business. At the worst you have to remove the glove box which is about 4 screws at the most but usually it is a couple clips and the filter is replaced. I will have to say that the dealerships are slowly becoming the repair place of choice, for 2 reasons. Today’s vehicles are becoming dependent on information to repair, special tools, test equipment, and techs with considerable training and skills. Many of the independent repair shops either cannot afford or don’t have access to many of these. So there quality of repairs is suffering, making the dealership the place of choice. I recently had the intake manifold gasket replaced on my Bonneville and had to return to have a antifreeze leak repaired, they replaced a connector at no charge but I still have a slight leak and will have to return again. A nuisance to say the least. I thought this was going to be a place to go for repairs but maybe not. They overfilled my crankcase at the last oil change this should have given me a hint.Really don’t know what the answer is. The right to information act is a beginning but far from becoming a reality. The price of test equipment is not going down, and the availability is always going to be a problem. A lab scope is almost a necessity to diagnosis any ignition or fuel problem and a scanner has been for some time, there price is going down however but there uses are limited.
