Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello and good morning. You will need to view the firewall from the passenger side and underneath the vehicle. The evaporator drain will come out of the firewall relatively low and on the passengers side. It will be around 1/3 of the way from the passenger side across the firewall. If it utilizes a rubber boot, you may be able to squeeze the boot to start fluid flow. If you do not, use something like a pipe cleaner to probe around inside the hole you find for the drain. You want something firm yet flexible so it will not cause any damage in the case. Be prepared for significant amounts of fluid to drain, once you clear the obstruction.
