I need to remove q-bond from my car door

google your Hotpoint model number include parts, Dowsil is approved but is price prohibitive.

The piece that is on the glass is glued on with an ultra violet cured adhesive, or a two part epoxy adhesive. The last one I did was cured by the sun in 24 hours (mix, set and cure).

My best advice here is to pay a specialist to do it. they will be able to do it quickly, easily and they pay for it if the glass breaks during fitting.
For Door windows you will need to remove the door card on the inside of the door to get access to the door winder mechanism, frame and rails for the glass. You will probably also need to remove the door trim the glass rises up through to give you more room to get the glass in. Replacing the glass isn't too difficult but it is a two person job and will probably take at least a whole day to do. As the new window glass is curved it will also take a lot of twisting and rotating to get it in without breaking it.
The rest of the windows, like the windscreens and rear quarterlight windows, are bonded in with a strong adhesive which needs to be cut out and the frame cleaned before the new glass can be glued, (bonded), into position.

You can try a 'superglue' used for sticking interior mirrors back in place. images below are generic. Most car accessory shops will sell suitable glues:

Or you can try a two-part epoxy type glue:

Get a rear view mirror adhesive kit at your local auto parts store. It will have the instructions on how to apply the mirror back on windsheild with the adhesive. I hope this helps!

You can buy a special bonding adhesive at a parts store to fix this. Usually there is a piece that the mirror attaches to, which is glued to the windshield. You will need to follow the instructions on the bonding adhesive, which will include cleaning the area where you will attach the mirror, and usually you separate the base mount from the mirror, glue it, hold in place with pressure for about 1 minute, reattach mirror, and you will be good to go.

It should just slide out. You might have to use a little bit of force

Call a automotive body shop supply, they deal in all kinds of chemicals, this includes adhesives for car repair, they might be able to help u, almost anything will damage the paint that is strong enough to remove this stuff
