What's the best way to remove a seized on wiper arm ?

[FastLife91]

Car is a 57 plate 1.9 CDTI Vectra.

I want to replace the wiper motor assembly as the linkage is broken on current one, I got whole assembly complete with wiper motor for £10 and this also included 2 wiper arms and the cowl.

However I have one wiper arm off, It was seized but I managed to get it off with a wiper removal tool, however the other wiper arm on the driver side is seized on also and does not seem to want to come off even after using the wiper removal tool on it as well.


any ideas on what to do next ?


thanks

Spray it with WD40 or a penetrating lube, and tap it gently with a hammer and pointy thing to break the corrosion which causes adhesion.

Sometimes the only way is to drill it out completely but this depends on the types of links/screws used.

Not sure if you're talking about the assembly that's off the car or the wiper is stuck on the car, but if you can safely apply heat without damaging anything else then do so. And I mean lots of heat.
