Check of serviceability of functioning of the driving electromotor of the fan of a heater and its replacement

Cars considered in the real Management are equipped with system of the additional safety (SRS) which is better known as a safety cushion. Before performing any works near assembly of a pillow or a steering column, without fail disconnect system in order to avoid receiving traumas as a result of its casual operation, – disconnect from the battery at first negative, then for a positive wire and wait not less than two minutes before starting service of the components located near sensors of directed overloads (see. Onboard electric equipment). Isolation and contact sockets of electroconducting of a chain of SRS are painted in bright yellow color. It is not necessary to connect any diagnostic devices to this chain!

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!



1. At a standard complete set the fan of a heater is a part of cooler assembly To/in and is located on the right under the dashboard (address to an accompanying illustration). On the models which have been in addition equipped with a back heater of salon, the fan of a heater is located under a passenger seat. At refusal or violation of serviceability of functioning of the fan of a heater first of all check a condition and reliability of fastening of all terminal connections of the corresponding electric chain. Make sure of completeness of a charge of the battery. Estimate a condition of the corresponding safety lock (see. Onboard electric equipment). The probability of failure of the driving electromotor is not excluded also.
2. Find the socket of electroconducting of the fan.
3. If the motor does not function, disconnect from it electroconducting, include ignition and make sure of serviceability of giving of a food, at the switched-on fan on the socket tension of the battery should take place. If tension is absent, therefore, malfunction of electroconducting in a power-supply circuit on a site between the switch of ignition and the switch of a choice of a high-speed mode of the fan, the switch of management of functioning of the fan, the main relay of a heater, or electroconducting on a chain site between the switch and the electromotor takes place.
4. If tension of the battery is present, connect electroconducting to the motor, from the back party of contact knot connect a wire crossing point to the No. plug 2 sockets and earth it on weight, – if the fan does not earn, it is necessary to check an electromotor condition. By means of the wire crossing point protected by a safety lock submit a food directly on one of contact plugs of the motor, the second plug earth, – if the motor does not start to rotate, replace it.
5. At the serviceable electromotor it is necessary to check a condition of resistive assembly and the switch of a choice of a high-speed mode of the fan, – remove assembly the control panel (see. Onboard electric equipment) also check distribution of provodimost between switch plugs in each of its provisions. Remove resistive assembly and check it on conductivity existence between the corresponding contact plugs (address to an accompanying illustration).



1. If there is a need for replacement of the electromotor of a drive of the fan of a heater, disconnect from it electroconducting and air lines then remove its fastenings and lower the fan down (address to an accompanying illustration). In case of need the krylchatka can be removed and rearranged on the new electromotor. For the purpose of ensuring access to the electromotor of the back fan on models of the corresponding complete set it is necessary to remove a passenger seat (see. Head Body).
2. Replacement of the electromotor of the fan of a back heater demands To/in evaporator removal for what it is necessary to discharge To/in system at car repair shop. Give 4 screws and uncover the electromotor. Give four screws and unhook three spring clamps then remove the heater case (address to an accompanying illustration).
3. Give a nut and remove a krylchatka of the fan (address to an accompanying illustration).
4. Give the screw and remove the fan electromotor (address to an accompanying illustration).
5. Installation is made upside-down. Track reliability of a tightening of fixture. Check level of cooling liquid, start the engine and make sure of absence of leaks and in serviceability of functioning of the fan.
