Anybody else have anthing? I've noticed the same symptoms as the OP since summer started.
Mine only has real good cold air on rainy or cloudy days or cool mornings. When it decides to work on a sunny day, it's just cool enough(with a trick).
-Watched my fan speed today with ac on. Never saw over 900rpms on the fan. At idle with ac, fan speed is anywhere from 380-500rpm, usually on the lower end. At idle with ac off it seems to stay in the mid to low 300 range usually. Driving with ac, fan speed would hardly change, just hold in the upper range of 380-500, sometimes higher.
-I have no overheating issues at all. EGR is stock and connected and cleaned recently. Towed my boat(~8500 lbs) real hard last weekend seeing what temps would do. Got up to max of 216 oil and 208 coolant, oil would come down to match coolant and build back up.
-Weird thing here. I'm in an Excursion with rear a/c. When only the front is on, it rarely gets cool enough. I switch on the rear a/c, rear vents blow out cooler, and then the front vents start blowing cooler, which is what makes this bearable.
-While towing, the ac blows warmer then when empty. Just started noticing this 2 weekends ago.
Hopefully someone reads all this. Thank you. Any Ideas?!? Is it worth the money putting in a new fan clutch? I have an appointment to get it done, just not sure if the $400 will make any difference here. I'm planning on finding an ac place to check out the refrigerant tomorrow to rule that out.
