The blower control switch is dead on my 96 Sportrak and some bright spark has previously bypassed it with a rocker switch wired direct to the blower connector tabs thus giving full blast or off. I've found the resistor block and the small one has broken (replacments on the way from RS). The manual suggests also if the blower is faulty to replce the relay but I'm buggered if I can find it. It's not where the diagram in the service manual has it. Any help is much appreciated, with the colder months on the way I'd like to have more control over the heater!
