Thanks for the instructions...just wanted to say that they worked well. Similar symptoms as mentioned by others....no warm air, and clicking noise coming from behind the console.
It took approx. 3 hours to complete the process of removing and replacing the actuator. Previously, SLEB posted that you need to remove three screws for the actuator but can only get two screw when installing it.
Good news...with a long extension and a ratchet, I was able to get the 3rd screw (top) in - coming at it horizontally through the lower instrument panel ... I used a light to illuminate the screw/actuator which helped a lot.
The replacement actutaor part number was 1L2Z-19E616-CA
Just replaced the rear ABS speed sensor today as well - resolved the ABS light being lit on the dash. (it took an hour)
2002 Explorer XLT 4X4 in Canada - 322,000 km (200,000 miles)
Replaced alternator, broken rear springs (both), rear wheel bearings (twice), front bearings need replacing, rear windshield wiper motor, front passenger power window regulator, plus normal maintenance.
Overall, however, I still like the Explorer.
Thanks again for the information
