Screw seized on door panel

I have 2 screws left on the driverís side door panel that are seized. I have been regularly hitting it with PB blaster which has worked wonders on everything else so far, but still those 2 wonít budge. Iím guessing since itís a vertical surface the oil isnít soaking down into the threads as good as it could be. The heads are starting to strip so thatís a second problem. I did get one out yesterday with a screw extractor and an impact gun at low speed, but that was touch and go. So now Iím left with these 2 and I have so much work to do on the doors.

Am I completely missing a trick of the trade here? What can I do to get these stupid bolts out?!

PS: Go easy on me, Iím a girl.

I had a similar problem on my doors. I would do exactly what you said, except I was also putting a screwdriver into the heads and tapping them with a hammer to just help the PB Blaster get distributed. I got all but one off and ended up having to drill it out and use an easy-out to get it out. My heads were also fairly stripped from presumable the last owner trying to do the same thing.

Re: Screw seized on door panel

If worse comes to worse. Drill off the heads, leaving the shafts. Add a little heat, tap with a small hammer. Attach a vise grip to the shaft and try to back it out. After the heads are drilled off you should be able to remove the panel and have better access to the shanks. Good luck. Make sure to run a tap through all the receptacles prior to assembly to remove existing rust.

Re: Screw seized on door panel

like mentioned above, I find it easiest to drill the heads off, remove the panel, and deal with the screw shanks that are left..

grooming the heads of the screws with the panel on is asking for trouble, very difficult to work there without damaging panel..

sharp drill bits, strong low speed drill, patience.. use controlled pressure to get big chips but don't want to run off into the vinyl..

once the panel is removed, soak screws with copious amounts of pb blaster, kroil, wd, whatever penetrant you prefer..

use vice grips with a good sharp jaws and square edges that will allow it to bite every bit of what's protruding..

don't want to mangle what's left into a nub, get a solid bite and work it loose..

sometimes the corrosion is heavier on the tail of the threads (part inside the door) so it may thread in or tighten easier than out..

not far, just enough to break it loose and then work it back and forth, a little more loosen each time until it runs all the way out..

chase the threads with a tap and lube.. I believe mine were all 1/4"-20 but you'll need to verify that on your doors..

by the way, I've had to do this for several screws out of each of the four sets of panels I have removed so don't feel bad..

good luck!

Re: Screw seized on door panel

Agree with above. As drilling goes, in case you're not used to it, apply oil to the bit and/or screw. Use the smallest bit you can get away with without busting one, you shouldn't need more than an 1/8" for a 1/4" screw. Smaller if the problem is the stainless steel above the panel, those screws are #10.

Bits generally bust because of not shooting straight right. Personally I'd use a good bit, IRWIN has never let me down, drilled 3/8" grade 8 bolt for me too, through the thread top to bottom (yikes).

Spraying with water as you drill helps too, bits like to be cool. Defeats the purpose to have a bit spin going nowhere.

Re: Screw seized on door panel

If you can find them, use left hand drill bits. If the bit catches, it just might back the screw out.

Re: Screw seized on door panel

I had 1 or 2 of the nuts on the door come off when I was used some force getting the bolt out. I replaced the nuts with 1/4-20 cage nuts from the hardware store. So if you get forceful with it and that happens, not to worry.

A nut that survived

Re: Screw seized on door panel

As you run the drill thru the screw, stop and see if the heat from drilling has loosened the screw up.

Re: Screw seized on door panel

I had to do this recently. Drilled the head off and used a vice grip to remove the treaded part.
