Look at the hinge area of the door and look for a small stepped bar that holds the door in positions when opening. It moves over a small roller. They have a habit of rusting up and instead of rolling will jump over the notches. Tyr some oil or grease and see it that fixes the problem. Some oil on the hinges may help as well.

SOURCE: Passenger door won't open from inside on 98 S70

You will need to remove the door panel from the inside and look for any missing links or bent parts that are causing the problem. Use a trim tool to get the panel off. Unscrew the arm rest. Have a magnet on a telescoping wand hand to fish any parts that fell to the bottom of the door out.

SOURCE: Door will not slide automatically; emits loud beeping noise

Something similar to that was happening with our Odyssey...the beeping when you are driving whether it's ongoing or intermittent is the "safety alarm" letting you know the door is not closed. The power lock is not engaging. What I do when I get the beeping while driving is hit the Door Close button. It causes the door to attempt to engage again. To fix it...we first cleaned out the space below the side running board (kids were hiding crayons and things in there), then looked for any obstructions along the top and bottom tracks. I sprayed a lubricant along the tracks (I'd suggest the dry lube kind...I used WD40 the 1st time and had streaks of it dripping down after driving), use a lube that has a long straw to spray in small places...and spray up into the track that runs the length of the middle of the car. Manually open and shut it a few times to get the tracks lubed, then try it out.
If you press the open OR close button by remote or in the car and get nothing...no movement/no noises/no beeping...then it could be the electrical circuit itself, the signal itself may be impeded...or the motor shot. Have you tried any of these suggestions before?

It could possibly be a shock or strut bracket.

SOURCE: Air conditioning fan makes loud noise the faster you ru it.

Concerning your broken vent -- this can be caused by a broken linkage or a malfunctioning servo motor as well. these vent have air ducts the sway back and forth to adjust the dual air flow function. if the servo o linkages are malfunctioning or not connected for some reason, it will not allow total control of the air flow and temperature range. Now, if you have a combination of a flow error and temperature error as well, thai can be caused by a combination of the two.

In this case, you will need to inspect the linkages as well as the servo motor function as well. in addition, i would test the air temp sensors for there operational value. they control the temp when you adjust the coll or hot function.

Concerning the Loud noise coming from the blower fan---

This issue can be caused by a misalignment within the blower housing or, it can also be caused by some minor damage within the motor itself, causing it to rotate in a erratic manner, in return, forcing it to rub against the housing itself. the best solution here is to extract this blower fan housing and inspect for lose fan propeller and motor stability. replace parts accordingly.

PLease rate and have a great day:)

Loud thud or bang type noise coming from the front passenger tire when I turn to the left or stop hard.


Sometimes noises aren't where you think they are. If indeed it is in that area, check your swaybar end links, these will make loud noises if bad. If they are loose, replace them with one's that are greaseable, like Moog. Also, could be your slip yoke on your driveline, take it out and grease it.

End links will cost roughly $70 for Moogs for both sides and about an 1-1/2 hours to replace.
The slip yoke is easy, approximately 15 minutes and some lithium grease.

Passenger window makes loud noise when rolled down


On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Pull back the weather seal and you should be able to see what the window is catching on.
I've seen cases where the lock cylinder comes loose and hits the window
