Hi, had the dreaded no heat only cold air or vise versa problem on my 2003 jeep grand cherokee, 2.7 diesel united kingdom model. when investigating the through glove box way of fixing this problem i noticed that the plastic was already cut out, sure enough it has been fixed in the past. problem i have is i noticed the blend door nearest to me was not moving. there is no measurable voltage at the terminal connector. the furthest blend door is working great. it all worked perfectly when i purchased the vehicle in July. checked all fuses, found number 26 15 amp fuse had blown, this fixed the cigarette lighter
but still no voltage at the servo.
cant understand has the other blend door working fine. just got it parked in the hot air mode for now, getting cold here now in blighty.
has any one else experienced this problem??? cant seem to find an answer on the net to this. Thanks, Scouse Jeep.
