Front air in my George boy cruse air won/t work keeps blowing 12 volt fuse. also has 2 light on the same circuit

moved you to RV from computer help repair
why not ask George boy directly or you local RV center.
tell them engine size and makers name first.
also if someone changed the engine all that can be wrong.
or call for RV service to your location.
or call any local engine mechanic. to help or fix it.
have you turned the engine over by hand (wrench ) on the front crank shaft end pulley bolt. see if engine this old is not seized first>
if started is dead,Id do that on any old rig.33 years old, lots will be bad. best is start simple, make sure engine has life in it still
a compression test failing, means .... overhaul time.

well go to the RV center and buy the books for the drivetrain.
or go to makes web site and ask for the same
what is there can vary Engine , Transmission and HVAC.
what makes you think any 2013 RV or car uses vacuum for HVAC dampers/ most are motor drive.(gear box)
dead blower is. (the front blower in dash up front?)
1: blow fuse.
2: or controls to blower failing,
buy the service manuals, for sure drivetrain and HVAC.

Bad fuse. Loose wire. Bad fan motor. Bad fan switch are all possibilities. Ck fuse first.

Have you looked on internet for that model - troubleshooting tips ?

The furnace and fridge both have control boards that may have problems. First check both circuit boards for built in fuses. Hopefully this is the only thing gone Replace the fuse and you should be good to go.

120-

AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

120-
VOLT
CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be
caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned "off"
.
Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.
