Well, the heatercore of an -88 9000 isnīt that good quality, so it may be changed already, but if it sinīt, I would consider doing it at the same time, just to avoid the extra work, since you will be messing around with at least the hoses to the core when you change the blower, there is a risk that if the core isnīt leaking yet, it will be afterwards. The blower speed control unit is not at the exakt same position as the blower itself (itīs not built in in the motor), itīs placed on the AC/ACC unit, you will be removing it while you are changing the blowermotor. So if your blower is working on full speed all the time, youīll need to replace that one to, but i donīt think itīs so hard to find a cheap one at the junk yard, just be sure to the right one, is varys throughout the years. Be carefull when you work with the blower speed control unit, make sure you disconnect power befor working with it, you should newer ground the speed contol unit, the casing of it is +12 V when the ignition is on, so if you accidentally ground it an the turn on the ignition, itīs gone. /Mats
