Help. Just had new engine and guts in my mgzr, problem now no heating on any setting, just warm air when driving.checked fuses all ok, have an old rover 200 foe spares can I use the heater motor from that ?
Regarding the fuses , could check this . Might help ?
According to the information I have the cigar lighter is a 10 amp fuse number 3 in the passenger compartment fusebox and the blower motor is a 20 amp fuse number 17 in the passenger compartment fusebox. Also in the engine compartment fuse box fuse link number 10 which is rated 30 amps controls the blower relay/cigar lighter relay and the heated rear window relay.
Update, checked all fuses and relays,changed the resistor pack which was burnt out so decided to buy a new blower motor only to find that doesnt turn???.
So im now thinking no power going to it, how can I check this and rectify the problem, by the way i am to mechanical solutions as a politician is to telling the truth.......crap.
Please help but be gentle.
Resistor packs are common fault as you have found . You will have to test for power at motor with a test lamp or meter . Also check that the heater motor you fitted is turning freely by hand and not jammed .
As per Wh the Resistor pack is usually a problem on the Car's. Whilst you say you got a new Motor which would have had a Resistor pack on same was it a new unit as opposed to a S/h unit. Check it is getting power and if it is then I suggest you return the purchased item for a replacement. If the Motor is not getting power then I suggest you sort that problem and reinsert the old Motor and purchase a Resistor pack ex E.bay (cheap)then returning the new Motor for a refund.
Taken new blower motor back for full refund, im now thinking theres more to this than meets the eye,
Thanks for help guys, gonna have to shell out ......again, for auto electrics to diagnose And fix. Will post result after who knows might help another cold driver.
Problem solved. Result.
Turned out to be quite a simple fix, I borrowed a volt meter to check the switches all power going to the switch but no output.
Changed the switch cost £3 local scrappy, I now have heater blowing on all 4 settings and its hot.
