Problem with VAR model (Normality test)

[thanhtung3008]

In my VAR model, after I had taken the normality test, the result showed that I had 3 equations in which the residual was not normal (out of 6 equations)
In other test, my model was passed.
Can these problems with normality test affect "impulse response" result? How I can solve these problems?
Because I am a student from a university and I have not learned VAR model in uni. I just learn by myself so please help me with these problems.
Thank you so much

Normality in VAR:
As far as I know:
1. Normality is NOT needed when Granger causality analysis of VAR and Impulse -Response of VAR
2. Normality IS important when testing cointegration via Johansen tests in constructing Likelihood Function.
