More dirty pictures!

MACS manager of service training, Paul DeGuiseppi turned archeologist when he dug under the hood of a co-worker’s 1999 Volkswagen Jetta and found a fossil where the cabin air filter should be.

Paul says this was the first time in almost 13 years that the cabin air filter was changed, evidenced by the date code of 30.07.98 right next to the VW OEM part number. While removing the original cabin air filter, he also came upon a mouse nest in the cowl, and the materials mice use for nesting such as leaves, feathers and stuff you don’t want to necessarily identify.

Not only was the cabin air filter dirty and frankly gross, it weighed about four times as much as the replacement filter from containing so much garbage.

 The shop who had previously been working on the car was neglectful and missed an opportunity for a sale for over 11-plus years!

When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
