"I really need you to find out the reason why it's not working anymore,"
Regarding the above please explain why the imperfect tense is used for the verb trouver (trouviez), I would have thought that either the present tense (trouvez) ... "you find out"
or the future tense (trouverez) ... "you will find out"
would correctly translate from the English text?
Thank you.
I believe that trouver is being used here in the present subjunctive, not the imperfect tense.
Conjugate regular verbs in Le Subjonctif Présent (subjunctive mood)
Absolutely. This is the subjunctive, which looks just like the imperfect.
Agree. Avoir besoin que “needs” the subjunctive:
