reggie Posted October 31, 2008 Share Posted October 31, 2008 The other day the heater started to play up & now doesn't work 99% of the time. First off the blower started cutting out & coming on when I went round corners which seemed very odd, thinking about it, it must be just coincidence. Now it doesn't seem to work at all apart from the other morning when I started it up the blower was going, then I went to the garage & when I turned it back on nothing..................& nothing since. Any ideas please as its bloody freezing............... The only thing I can think may have had a contributing factor was back in June. I went through some deep deep muddy water which came over the bonnet, in through the bonnet vents, through the dash & came out of the heater controls. Its all been working since though until the other day. Quote Link to comment Share on other sites More sharing options...
maxtherotti Posted October 31, 2008 Share Posted October 31, 2008 the heater blower speed control resistor is under the wiper panel so i would be looking in there first rob Quote Link to comment Share on other sites More sharing options...
DC_ Posted October 31, 2008 Share Posted October 31, 2008 Sorry for being a bit thick here, but "under the wiper panel"? Mines took a wee while to blow the other day but seems fine now so if it's starting to go i'd wanna keep on top of it. Quote Link to comment Share on other sites More sharing options...
reggie Posted October 31, 2008 Author Share Posted October 31, 2008 the heater blower speed control resistor is under the wiper panel so i would be looking in there firstrob Thats what a friend suggested, also said it could be the motor in the dash.........

maxtherotti Posted October 31, 2008 Share Posted October 31, 2008 the panel behind the bonnet where the windscreen wipers come through some call it the decker panel others call it the scuttle panel has loads of names but thats where it is rob and i have been thinking normally when the resistor fails the motor will still run on speed 3 (resistor is for speed 1 & 2) but the motor feed still runs throught it and if yours is covered with wet mud could have corrded the terminals so bad they have broke off??

maxtherotti Posted October 31, 2008 Share Posted October 31, 2008 no over looking the obvious have you checked the fuse?? rob Quote Link to comment Share on other sites More sharing options...
reggie Posted October 31, 2008 Author Share Posted October 31, 2008 I didn't check the fuse as it was intermittent before it stopped totally but worth a look. So you think it may be the resister pack? Quote Link to comment Share on other sites More sharing options...
maxtherotti Posted October 31, 2008 Share Posted October 31, 2008 if it was my car with this fault the first thing i would do is check for voltage supply to the motor if none there check at resistor pack then at switch then back to fuse if you have no voltage at fuse then fuse box is shot but at least this way your working in a methodical manner and if it is a wiring not component fault you know what area to be looking in could also be a simple switch/resistor/motor failure too tho with electrics never over look the obvious (i talk from experiance here ) and work in a methodical way rather than dashing from one point to the next rob Quote Link to comment Share on other sites More sharing options...
steve_d Posted November 1, 2008 Share Posted November 1, 2008 What model and year are we talking about? My 87 does not have the resistor pack under the decker panel. I would be starting at the blower control as that is the easiest to get at. The decker panel can be a pig to remove. Seem to remember my resistor pack was behind the switch panel. Can only talk for my wiring, so.... WLG = live from fuse 7. RB = high speed which goes to fan motor but via a connection on the resistor pack. So if you have volts at WLG wire on blower switch set the blower switch to high and you should have volts at RB wire which goes almost directly to the motor. Do you have A/C? Mine has so there is also a relay in the circuit. Took photos of mine when it was stripped down but do not have access to them at the moment as my son has our server shut down for repair.
