I had a similar problem - all or nothing blower. I tackled mine at the same time I did the wiper motor as I had the bulkhead off. My resistor (1989 Sport) is situated in the front of the blower fan. The top of the blower cowl is held together by a wrap round metal strap. Unclip this and lift the top half of the cowl. The resitor points down in the centre of the blower body and is a push fit. In truth I never even took mine out. I squirted loads of lubricant into the centre spindles of the the two fan rotors while they were running. I tried silicon spray first but then WD40. The latter worked the best although it smelt inside the car for about a week. The fans were obviously sticking and therefore the voltage reduction applied by the resistor was insufficient to turn them. The oil freed everything up and also got rid of the squeak/squeal that was there before. Everything on mine has been working 100% ever since - did this about March. Wiper motor repair has also held up. Hope this helps!
