If you have a spider phobia or are OCD and are freaked, here is your solution.
1. Get your shop vacuum and clean out all the crap at the air intake screens.
2. Start the truck, A/C off, fan off, vents set to floor, and close the recirculating vent.
3. Drive or idle to get the temperature hot.
4. Park the truck in the sun, keep engine on.
5. Turn the temperature control to max hot, fan to high.
6. Let truck idle for about 5 minutes like this to get the inside good and hot. This will cook, or desiccate, or pulverize the spider in the fan blades, if it happened to make its way inside past the filter. You can get out of the vehicle during this time, in case spider parts gets flung out of a floor vent.
7. Open the vent to allow outside air to come in for about a minute, then close the vent again. If your vacuuming didn’t get the spider this will suck that sucker in and will get caught by the cabin air filter.
8. Let the truck idle 5 more more minutes.
9. Turn truck off, shut door, lock it up.
10. Let it sit in the sun to stay hot for several hours to continue to cook the spider in case it is stuck in the cabin filter.
11. Open cabin filter case, remove filter and check for spider. Vacuum out the fan, filter, and filter box.
12. Vacuum the floor mat to get rid of possible spider parts.
13. Congratulate yourself and have 2 to 3 stiff drinks to calm your nerves after this ordeal! :cheers:
