A/C issues after Harmonic Balancer Replacement

scbarney · 07-16-2019, 05:29 PM

Got car back from a harmonic balance replacement yesterday. The shop said all belts and pulleys looked good besides HB. BUT when driving home with A/C on I heard squealing from belts every minute or so (nothing with A/C off).

Today I was testing to see if issue was still there. After a little squealing for first few minutes of driving, the noise completely went away, BUT now no cold air from A/C, just warm air.

Is it the belt or A/C compressor?

When I picked up car from shop the A/C was on, but noise was faint until I was a few miles away. Should the shop have checked/noticed the issue?

Thanks in advance!

Isn't it like 2mm smaller? Original was know to slip. Mine would do it when I first started ac on a hot day then It would work fine afterwards

And you aren't supposed to reuse the stretch A/C belts from what people say.
