I'am not aware of Country Coach ever offering over the road A/C unless you had a Prevost conversion. Also known as bus air -OTR

Really, so with the normal (car size) a/c compressor in the engine room plus another additional rather large compressor for over the road -OTR A/C.

What your saying is your 2007 Allure has no roof A/C units, right.

Here are the most common types of RV A/C systems; Dash air Roof air Cruise air OTR A/C - normally only available in Prevost Conversions. This system runs the A/C cold air throughout the bus on the flat work below all the windows in the bus. Only works while the engine runs. It's the system that's normally in your passenger buses. As an $20K plus option i said to keep the entire bus cool while driving. Thus the name attached OTR bus A/C.

I'am not trying to start a mass e-mail but it helps to keep terms straight.

According to the schematic for my 2000 Magna, there is a 20 amp circuit breaker in the circuit for the rear fan and solenoid for the bedroom OTR air conditioning system. However, I have no idea where it is located; sorry.
The breaker may be on or near the front run board in the bay under the driver's seat as the circuit is fed from the ignition solenoid.

Never heard of cruise air so in the interest of learning something new what is the definition?

OTR AC is so labeled because it runs off the engine when you are ''traveling "Over The Road"?. I don't know where you get the idea that it belongs exclusively to Prevost Bus conversions. CC has installed OTR AC for years. In recent times the smaller low end coaches had it only in the front dash so I guess that you would label it dash air but everyone that I know often calls it Dash OTR.. In the higher end larger coaches CC installed a larger system that was capable of providing OTR AC in both the front and the rear of the coach thus keeping the entire coach cool while on the road. Often dash OTR AC will not keep up with very hot conditions so people will resort to running their generator while traveling to be able to run the roof air units.
You have me at a disadvantage with the term 'Cruse Air'. While I am sure that it may be a legitimate term for some sort of AC system I personally do not know what it means. Likely others on board here will jump in to provide me a much needed explanation. Virtually everyone here knows what we mean by OTR AC. You have provides four terms but only one explanation of your meaning. I doubt that it will convince us to abandon our long standing understanding of OTR.
Sorry to be so blunt but you have also not lived up to a long standing tradition here of signing with your Name, Coach Model, Year, Length and Coach Number. Now that can start a mass emailing.

Tommy,

They changed the wire harnesses very little from year to year so your coach should be similar to my '03 Magna. The rear A/C fan circuit is protected by a type 2 self resetting circuit breaker in the electric bay under the driver's seat. It is a 20 amp breaker on wire #208 on the ignition switched bus bar. On mine it is the bottom circuit on the second full height bus bar in from the door.

Good luck.

OTR A/C is the A/c system put in passenger buses which cools the entire coach with no other A/C system in operation. The term IS exclusively used in the conversion business to separate dash air , roof air, and cruise air systems. CC has installed OTR air for years is correct but ONLY in bus conversions. An example would be Prevost shell, conversion by CC. They CC did not do a very good job of altering the system as it worked well but in the CC wisdom at the time changed the system. In today's world this has become a nightmare for current owners. Price of CC Prevost conversions sell at major reduced dollars to others.
Of course Don, dash air is over the road air. In shop terms it would be somewhat confusing if you ID your OTR A/C as not working. What you were really talking about was your dash air. So now you have an example of correct terms.
In best definition of cruise air I'll explain with a example that boaters with A/C on their boat have cruise air units or AKA chill water A/C. The sea water is pumped aboard as the cooling factor. If this system is in a bus and has been installed by the convertor air is drawn from under the bus (cool air) while driving fresh air drawn in while driving . Cruise air units are usually 3 or 4...plus dash air.

I'am not trying to change anyones mind on anything. Go ahead and use the incorrect terms to techs and you'll convince them you don't know what your talking about. On that point I'll rest my case, some members will understand and others don't really care.
AL

2000 Affinity #5851 BTW.. roof airs and single dash air.

To go along with Al's definition you wouldn't take your toad into the shop and tell them your OTR air wasn't working. You would tell them your dash air, or rear air in large SUV, wasn't working.
The dad air in my gasser or any DP is just like the system in your toad. A true OTR is very different and a standalone from the engine.

Over-the-road AC is a term used by country Coach for the bedroom AC system. This system is run by the same engine AC compressor as the dash AC. If you have a Magna or Affinity, you have this system--we have it in our '95 Affinity. If you turn the AC compressor on at the dash, you have AC in the bedroom when you turn the bedroom fan on, and it is quite functional. You have this system on your Affinity.--if it works.

That is like the rear air systems in full size SUVs.

[You wouldn't take your toad into the shop and tell them your OTR air wasn't working]
This is true, but then the toad doesn't have roof air either, so I wouldn't have to differentiate between the two systems. Over the road air conditioning is too generic of a term to apply to a single system. A quick Google search reveals that Prevost refers to their Bus Air as 'Full Air', so it would seem to me that the industry has adopted generic terms for a specific system.

My old Magna also has the Politically Incorrect OTR system as described in the manual.

On my engine compressor driven dash and bedroom system that CC labeled OTR, there is a dedicated dryer and expansion valve attached to the bedroom evaporator. These are located in the overhead rear cabinets on my rig.

The common components are the compressor and the condenser for the dash and rear cooling systems. The Compressor Clutch is engaged by the Dash control only.

If the fan blows with the dash ac engaged, the bedroom air should be as cool or cooler, in my case, than the dash air. (No windows radiating heat.)

If the air is not cool in the bedroom but is at the dash, you could have the Dryer and the Expansion Valve replaced in that system to try to restore the cooling. I just did that for the first time in 19 years on my rig.

The parts are about $60 and the 134a will run $40 per lb installed after a vacuum test. My 5 lbs cost $260 installed less the recovered 134a.

Labor for installing the dryer and expansion valve should be no more than 1 hr direct labor plus parts sourcing from NAPA. Once the system has been vacated, it is just 4 spin nuts to be released from the old components and 4 to install the new components.

The compressor clutch and condensor fans are controlled by a fuse in the Front Run box and a relay in the same location on my old rig.

As far as I know all the cooling parts are working only the blower which in my coach is under the bed maybe CC should have labeled it UTB (for under the bed!!!) or maybe OTR stands for over the rear:).

LOL nice one Tommy and good luck with finding problem.
If it is only the blower that doesn't work I would start by checking for voltage at the switch and then follow which ever direction you need to from there.
