Folks,
Any ideas on the following?
V reg 4.0 P38 with the digital HEVAC unit showing the warning symbol suggesting something is up. The unit is right as around March time the blowers stopped working. The HEVAC unit was swapped out for a new unit, but no change resulted and so the original was put back again.
When I put 12v directly into the blowers they fire up without any trouble but they don't when instructed to do so by the control on the HEVAC unit.
I have inspected the fuses, relays and have had the fuse box apart and there is no sign of any components burning out. Continuity tests on the circuit also appear successful. The only other thing that I noted was that the fans (assuming linked to the A/C system) behind the front grille also don't move at all.
Any thoughts or pearls of wisdom would be greatly appreciated?
Cheers,
Magoo
