Where is trap door located? - 1995 Nissan Altima

No spring , no trap . Has electrically controlled actuator that opens an closes the temp blend door . Your best bet ,take it to a qualified repair shop , as the dash needs to be pulled to replace this actuator .

You may have an air-mix door that is not functioning properly. It isn't operating to allow air flow to change direction and go through the other vent locations.

1. A trap door can simply be jamed.
2. You could have a bad vacume hose/connection, some use a vacume to open and close trap doors. Particularly from the floor vent to the upper vents
3. Some use electrical componets, an actuator to open and close doors.

This is very likely an easy repair.

Hello,

The drain plug of the chevrolet 2004 trial blazer is located under the engine skid plate it is with the oil filter. And there is a guard to be removed. There is a trap door before it.

The skid plate door is located by the drivers side door, directly midway underneath the vehicle. You will need a flat/phillips hear screwdriver to open the trap door. Do not worry, the screws are 'loss-proff' and will not fall off the trap door plate. Once this has been removed, the oil drain plug and oil filter are now visible and accessible.

Oil change should not take you more that 15/20 minutes.

Hope this helped.
Take care and good luck

The oil filter is not on the engine but just behind the front bumper in the engine compartment under a trap door marked "oil filter access"

I have a 1995 blazer in the family, and the oil filter and access to it is located behind a plastic trap door under the front of the car, beneath the motor. Hope this helps.

The battery is behind the passenger front seat, in a trap in the floor.
It the same on a gmc acadia et buick enclave.

See the pictorial representation here...

The oil drain plug and oil filter are under the engine skid plate. You need to remove the trap door to see. The skid plate door is located by the drivers side door, directly midway underneath the vehicle. You will need a flat or Phillips-hear srewdriver to open the trap door. Don't worry, the screws are 'loss-proof' and will not fall off the trap door plate. Once this has been removed, the oil drain plug and oil filter are now visible and accessable (how smart is that!) Typical oil change and oil filter replacement time = 15-20 mins. for a familiar shadetree. p.s. The Inline 6 (24 valve - 4.2L) takes 7 quarts of oil. Good luck!

Here is i cant make it any easier :-) .

You didn't post the size of motor but once you drop the skid plate, you will see it.

in your fuse panel (prob under trap door in bottomr of dash) you will find a serise of blac cube's (relay's) use the diagram on the trap door to locate wiper motor relay odds are it's shot
