I had a 90 Cutlass Supreme that did that too. I just got into the dash and forced the arm on the main gate open.

The heater core is located on the passenger side of the vehicle. If this has been bypass the core is surely leaking. The heater core pipes should be visible from un der the hood, passenger side of vehicle towards the firewall. keep me posted, and keep an eye on that heater core, there is reason for the prior owner not to have heat.

The blower resistor may be going bad and need replacing. Does it do it only on one or any fan speed? I'm not sure where that particular part is located for it has been number of years I have looked at vehicles older than 18 yrs. but I hope this steers you in the right direction.

How do you know it's surging? In any case, about the only thing that can cause this is a faulty regulator in the alternator, or a poor wiring connection (e.g. battery cable or at alternator).

Have you checked the vacuum line with a gauge? If so, how many pascal units does the vacuum line read? Vacuum gauges are around $5. Furthermore, I believe the design is sealed vacuum only system. The solenoid could be bad, but to my knowledge it is not an electrical component. A split in one of the vacuum lines could be cause of your problem. You would have to trace the all the vacuum lines back to the source to find the problem. You would need that gauge to detect a leak in the system. Could also replace all the vacuum lines on principle since the vehicle is going on two decades.

Behind the firewall? Sounds like you need to take your dash off and get at it from the inside.
