Order of inspection
P0529 Fan Speed Sensor Circuit Intermittent Medium
The P0529 code means the fan speed sensor signal cuts out or jumps from time to time. The main effect is imprecise fan control. Intermittent faults are almost always a poor contact or a damaged wire, so you have to reproduce the problem to find it.
