I took my van to get winter tires removed. They did a 10 point inspection and told me my cabin filters needed changing. They quoted $50 for this. I bought the part myself for $20 and replaced them myself. I didn't even know there were cabin air filters in this van. Is there any other maintenance that is this simple that I can do myself?

 

That all depends on your mechanical abilities? not sure abouth the 02, but in my 01 there is a fuel filter under the drivers side that can be replaced with limited abilities. the air filter in the 01 requires some patience and imagination to get in and out, the pcv valve is fairly simple to replace, check the owners guide for maintenance intervals, and judge yourself accordingly what is within your capabilities
