Do temperature changes and humidity levels in different parts of Pakistan affect the functioning of the purge valve in Alsvin?

Could frequent weather shifts humid in Karachi, cold in Murree cause condensation o r clogging in the purge line o r valve?

Yes. The EVAP system is sensitive to environmental conditions:

Humidity Karachi can lead to moisture accumulation inside the EVAP lines, corroding internal valve parts

Cold weather Murree, Abbottabad can cause condensation, freezing, o r delayed solenoid response

High heat Multan, interior Sindh causes plastic lines and seals to become brittle o r warped

These shifts accelerate valve failure if regular cleaning isnt done.
