Salamualaikum,
I was in the same position during Ramadan where I wanted to make the effort to actually learn to read the Quran in Arabic fluently. Prior to this I had always memorized Quran through reading transliteration ( Arabic spelt out in English I.e Bismillahi Rahmani Al-rahim) simultaneously with hearing my favourite recitors, as well as follow the translation after). I was honestly finding the whole reading Arabic quite daunting. I too know the alphabet and sounds, but joining them together was always extremely difficult for me. Plus my understanding of classical Arabic is limited. However there are some amazing YouTube videos for Arabic lessons, I was very surprised and you learn so much in such little time. I would highly recommend one lady, I found her teaching style and the order of her lessons to be very good with a comfortable flow.

If you follow the rest her videos according to your level, you will see STEP 1, STEP 2 until about 13, and other videos are labelled via subject matter.

Learning is specific to the individual though so if the above isn't helpful I would recommend you have a look around at other teachers on YouTube until you find the one you find most useful.
Good luck.
