Wipe water pump or just frozen at C4!?

Hello C4 municipality, I have a problem with my wiping water pump.And this is not working for some time.I was therefore already with my , who told me that this can be quite frozen at the prevailing temperatures. But now we already have the whole day + temperatures, but it still does not work. What should I do according to your opinion? Should I wait a few more days or immediately to the ? nter the guarantee or do I have to pay for it myself, because it is not a cover? I thank you already in advance for your help! Greeting Robert
